SMath Studio

SMath Studio box
 
 
 
 
 
 
 
 
 
 

Tiny, but powerful mathematical program with WYSIWYG editor and complete units of measurements support.

It provides numerous computing features and rich user interface translated into about 40 different languages. Application also contains integrated mathematical reference book.

Free for personal usage! Plans for Organizations are available!

Application can be easily extended based on your needs. Built-in Extensions Manager tool allows to get access to hundreds official and third-party resources of the following types: usage examples, plug-ins, SMath Viewer based applications, snippets, interface translations, interactive books, handbooks and tutorials.

Znakomite narzędzie, nie tylko dla studentów. Oby SMath rozwijał się nadal. more...

Any case of "if" statement is available now.

Approximately equal operator is available now (see Options dialog to set the accuracy):

Hi Andrey,

I see the "Approximately equal" operator accuracy varies from 0 to 15. What does this value actually represent?

Hi! It is an accuracy of the "Approximately equal" operator. F.e. if the accuracy is 0, then pi≈3, if 1, then pi≈3.1, if accuracy is set as 2, then pi≈3.14 etc.

Best regards.

Hi Andrey,
considering that the "accuracy operator" parameter that regulates "approximately equal" is unique, wouldn't it be appropriate that it is defined in percentage terms?

It's more than just the decimal place precision.

Regarding that.. I think "precision operator" more appropriately reflects the intended purpose.

This is a nice new feature.
Would it be possible to modify this value independent to regions?
Adding another submenu to region right-click would be awesome.
As in decimal places, exponential threshold, rounding choosing.

Hi. About the new approximately equal operator, another way to introduce it could be introducing a general infix operator, like in Mathcad. This screen capture is from Mathcad 6 running in Windows 3.11:

Clipboard02.jpg

For work with units you just need to modify the rhs by abs( a-b ) < UnitsOf( a-b )*TOL (or maybe UoM). Notice that also can be a solution for another features requests, like this one about inline division: https://en.smath.com/for...614_Inline-division.aspx

About the "Defined Integral supports units now" it is a major improvement, and while there will be many worksheets to update, it is a substantial and very welcome improvement. I do think that some kind of special announcement should be made. Also, if you plan to also modify solve and roots to accept drives, you may want to introduce the two improvements together in a future stable beta release.

Finally, many thanks to you Andrey and to all the developers who collaborate with the plugins for this excellent program.

Best regards.
Alvaro.

It's perfect alternative to Mathcad. The solution to make another namespace for measure units - is genious! more...

In the placeholders of the if() function type an "argument separator" symbol (comma or semicolon, usually)

The if without else will improve alot the readability of many scripts, thank you Andrey.

Thank you. But the problem is not because of eval(). She's somewhere deeper. My f3(x) and f4(x) limits are ainterp() of the table data.

Hi. Yes, I see that there are more than one issue with the double integration, even for some simple cases it is not sowed.

The question is why in the stable version integrals are calculated without problems, but in the new one it gives an error in the same places?

In other words, you declare a bug.
Designers need the document for doctoring.
... doctor since which SS version ?
1.0.8151.26932 OK
1.0.8206.25180 NFG

Yes, I'm reporting a bug. In version 1.0.8151.26932, dimensionless integrals with limits in the form of arbitrary functions are calculated correctly. In version 1.0.8206.25180, such integrals are not evaluated. The error "x/y - undefined" is returned.

It may be the XLS import ?
Try NOT import as a stand alone system.

It doesn't matter if there is an import from Excel or not.
