Hi, I have an error message that I can't figure out. For the most part, I have been able to learn Smath on my own, despite the absence of any user manual, and only a few brief tutorials written by users themselves (Liengme and Urroz). If there are any deeper manuals to recommend, I would be very happy to see links to them. I am still relying very heavily on my long experience with Mathcad to pick this up - but it's a double-edged sword because Smath doesn't do all that Mathcad did. One thing I would like is a list of error messages and their meaning. I can't find any references to this error expression on the SmathStudio website/forum. I could probably solve this for myself if I could find one. If I have missed an important source of information, I'm sorry, but please point me to the right place. The file linked below is part of a very long analysis that's suddenly gone bad on me - no idea why. Only the parts before the strange error are included. The rest is very very long. Thank you (in advance) to everyone that can help. I've also included a screen-capture of the offending expression:   ERROR.sm (77kb) downloaded 16 time(s).

Another solution is to put the equation in numerical optimization mode, and the error is eliminated.  ERROReval_r1.sm (83kb) downloaded 9 time(s).Best Regards Carlos

Wow, Thanks to everyone for your help. Firstly, I'm surprised that there's a simple solution to the expression that would not solve. It looks like I can globally select all the fields on a math page together and make sure they are all set to "numeric" just to make sure I haven't accidentally toggled something. Not that I am clear on just what "symbolic" is for... presumably if I play with "symbolic" expressions I can get Smath to simplify an expression? If I was a math teacher, or a student, I can see how that would would be fun or helpful. Secondly, thank you for volunteering the suggestions to augment the matrix for me. I was going to ask in a separate post... You guys are so quick! Can you clarify, please: is there no way to simply add a row or a column to a matrix? I can probably use the Insertcol() function, but if that's the way to go, then couldn't I use Augment() with the new columns? Thanks again!

I tried to click the "thank" button on the upper right, but it throws an error every time.
Jean, Ber7, CBG, know that I would if I could.

Thinking laterally... I created a fresh SM sheet, and put a single new 14x6 matrix in it, with no values filled in. I then opened it in Notepad, and also opened in Notepad the SM sheet with the incomplete 14x4 matrix. I was then able to cut-and-paste some of the values from one to the other. Where the element value is a simple decimal value in <operand> markup, it was easy to identify the correct lines. When the element is a composite of operands and operators for the values with exponents and units, it's not so clear, so I didn't try copying them. But it would be possible, if I thought it would save time. I also noticed that I could Find-Replace all the blank fields in the matrix (shown as "#" in the raw file) with "0". The Notepad method is faster than typing them all in 58 times. Quote: <region id="4" left="0" top="360" width="299" height="261" color="#000000" bgColor="#ffffff" fontSize="10">
<math decimalPlaces="4" exponentialThreshold="5" trailingZeros="false">
<input>
<e type="operand">Material</e>
<e type="operand">1.5</e>
<e type="operand">#</e>
...
<e type="operand">0</e>
<e type="operand">14</e>
<e type="operand">6</e>
<e type="function" args="86">mat</e>
<e type="operator" args="2">:</e>
</input>
With a matrix having >50 elements, this approach may save time do tedious re-typing of values, and definitely avoid typing errors (a SERIOUS ISSUE for me!).

Many have reported not working for them. However, many times I have been "thanked" Few more things: 1. The function replace(A,B,r,c) is an essential component in Image Processing. 2. You mentioned a long project ... Oh ! ... in that case is it wise to save a copy and work alternately on either one. Smath likes crashing and if so, the project is gone for ever !!! 3. Yes: you can augment/stack as in the attached. 4. Unless the project is naturally all "Numeric" compatible, you have to consider Symbolic/None as applicable by part. By default, a new work sheet is in Numeric mode. Cheers ... Jean Page2.sm (20kb) downloaded 22 time(s).
