  • Brilliant program. I have MathCAD but as they have gone for subscription based I am discontinuing that. Until now I have not found any design calculation that I cannot make using SMath Studio. I recommend to all of my customers to forget all spread sheet based calculations and go for SMath Studio. I have developed my own specialty engineering software and know how much work that is. Thank You Andrey.

  • Without a doubt it is one of the best tools for engineering, a good substitute for Mathcad

    by Marcel F. Chevalier S.

  • Probably the best free math program out there. As an electrical engineer, you can do so many calculations, e.g for designig drive systems and calculate protection settings, can be almost entirely automated using SMath Studio. With the huge amount of plugins you can push SMath in an high level. Thanks a lot!

    by Karsten

  • I hope you keep on developing this great software! Thank you very much, it is easy and very efficient. If someone could help you to bring it closer to a nice text editor, it would probably replace Word for many engineers and other scientists.

    by Dimitris

  • A very useful tool for engineers. Thanks a lot. Keep up the great work.

    by Bhargav

  • Best WYSYWIG math software, with outstanding cost/effect factor! In some areas even better thought than it's commercial oponent (auto complete, very big plugin database, small program size etc). Highly reccomended.

    by Bartłomiej Minor

  • SMath Studio is a great alternative to MathCAD. It is small and portable. I use it primarily for structural engineering calculations and for documenting my work. Many thanks to Andrey and the other developers for this great tool.

The new formatting options look promising.

Is there a reason for having all fonts downscaled to 80% in the pre-set configurations? I feel like compensating this by changing the font size to 12.

It is just because of diference between fonts: Arial and Courier New. Arial looks more tiny and a bit smaller. But one of the main changes is that now SMath Studio fully supports all kind of fonts to be used in equations, so you can choose any other one you like (it can be done altering C:\Program Files (x86)\SMath Studio\representation\settings.prop file with notepad) or increasing font-size (you can set size=120% f.e.).
In future I will provide UI of such kind of customizations, but for now I need to fix several issues related to new approach of rendering equations.

Thank you for the comment!

Best regards.

Thanks, Andrey. I already saw that the 80% only applies to subscripts.

What is the idea about keeping smath sheets consistent between users? The same document can have totally different appearance if the users have different formatting settings. If I scale the fonts up to keep them readable this might create overlapping regions if they were created with different settings.

Will there be a choice to make the settings being part of the document? Perhaps with the option that any other user can deliberately override it with his own settings. But then he is in charge for any mess created.

A short test showed the following issues (some of them might be matter of taste). I understand this is work in progress...

EDIT: The functions are deliberately set to italic in "Standard". Thus this can be fixed using a custom style.

Yes, here is the idea:
1) settings.prop file located in ProgramFiles folder which means it is a part of distribution package and should not be changed by user;
2) During several releases we will test the functionality, so I have allowed to change settings.prop file in order to find the best final presents together with community (final presets will result in more or less equal equation sizes, so changing them will not break layout of already created worksheets);
3) As soon as final presets is determined changing of this file will become impossible or it will be just not suggested anymore;
4) UI will be developed to allow anyone to change presets using some convenient dialog with appropriate options but all the changes will become a part of the worksheet. Meaning that settings.prop file will never be changed.

Regarding errors you found: almost all of them are known (I also have about 10 others). 3-rd one is already fixed and will be a part of the next build. Changes introduced are very complex, so I expect it will take some time to make something close to ideal. But we will do it!

Thank you very much, Martin!

I felt encouraged to play around a bit. I wonder why the font in math regions must be scaled to 120% to result in the same font size as in text regions of the same font.

Perhaps we are entering an era, where people become more picky about appearance issues of SMath sheets. The monospaced text regions become inappropriate now...

      <entry type="string">
        <font family="Times New Roman" color="#a31515" size="120%"/>
      </entry>

      <entry type="variable">
        <font family="Times New Roman" italic="true" size="120%" />
        <subscript>
          <font size="100%" italic="false" />

I think that ideally in the final draft each user should be able to define his own styles in the %APPDATA% directory, then the attributes of used styles should be included in the header of the worksheet, and the files in the installation directory left untouched. Same thing for units. Just my 2 cents Wink

Yes, and any user should be able to inspect/modify the definitions embedded in a document, perhaps in the document properties. This also applies for calculation settings. One could provide templates (examples?) with certain sets of settings.

Topic updated - new SMath Studio 0.98.6522 released.

New visualization approach improved and polished. The main change is that now SMath Studio knows if function/variable is defined by user or built-in and based on this different fonts may be used for visualization.

Note: new default formatting preset defined (I plan to use it in the upcoming stable release).

Please try and comment what you think.

Best regards!

Seems that the boolean operator "greater than or equal to" is not drawn, unrelated to vectorize

I experience some horizontal misalignments (caret position, empty placeholders, ...), I am the only one?

You are not the only one Davide. Mathcad 11 was not better at all.

There are few things those days [equation colors ...]
My preference are different by priorities:
1. Work sheet background color ON/OFF by click, like Mathcad.
2. Copy a section of work sheet, paste in IrfanView.
3. Few more Windows convivialities [ copy/paste images ...]

Topic updated: new SMath Studio 0.98.6523 released.

Many improvements done for equations visualization, restoring of performance on calculation and new functionality requested by Jean Giraud Offline implemented.

Please make sure you are using Default equations formatting (in Options dialog) as this preset is now priority 1.

Note: Linux problem is not handled yet.

Please test.

Impressive rate of progress!

At low resolution/small font size, the old formatting is easier to read, mainly due to the blur of the thin-lined operators.

Pasting multiple regions as image is nice.

When the maxima-plugin is downloaded from the gallery and the offer to search for Maxima is confirmed, then the setup dialog automatically closes instead of waiting for user input. The dialog can only be used after next start of SMath.

Feature proposal: pan the canvas by drag with the middle mouse button (as alternative to use the scrollbars)

Absolutely loving the changes (and software) - great work.Clap

Ive experienced some strange font scaling issues in in the two latest builds (using the latest right now). As I change the font size using either the settings menu or the toolbar option, the effect seems inversed and interacting with each other. Furthermore, they dont display the correct font scale value. As I press enter in the first image, one expects the typeface to get larger (from 7 to 14), yet the inverse happens. As I open the settings again, it displays a 10, and thus does not remember the latest changes. This effect doesnt appear to be linear, although its hard to notice when scaling.

The problem is not specific to any particular file, but occurs whenever I change font sizes, and persists through restart/new file.

The font settings under Tools> Options shouldn't have immediate effect at all. AFAIK this is just the default setting for new documents and can be overridden at any time by the toolbar entry for font size.

I'd recommend to clearly indicate the scope of the options in the dialog.

Some of them take immediate effect and there is no way to override the setting locally (per document or per region)
- precision of integrals
- multiple value results
- language, separator, equation formatting

Some of them are default settings applying only for new documents or for new regions
- result formatting
- solve interval
- color, font size...

BTW, I think that settings like multiple value results and precisions of integrals should have region scope.

The reported problem persists (post #11), but it is specified that it is only for the >= and not for <=, > , <.
