Fantastic free software. Have used it for several structural calculation reports

I'm absolutely love this app. It's a great tool for usual engineering calculations, and way more easier to use for me than matlab and others.

I just want to add that this small requirement to activate SMath Studio is a huge step to make this software much more powerful in the nearest future. Why? I will try to explain: I've created a company in Russia and we have a brilliant team of 3 programmers (strong in IT, math, physics). We were able to monetize a project and working hard to make our first clients happy (licensing server, courses, planning and features for companies). We are going to finish our current activities in a Month or two and then will start improve SMath Studio itself: new graphs, stable Writer, performance of the numeric/symbolic calculation engines, new files format (modern and stable) and much more - that is what we will do in 2023. Hope you'll enjoy the results. I just asking to activate a program for free! Nothing more... Best regards, Andrey Ivashov.

Rank: Advanced Member Groups: Registered Joined: 10/01/2017(UTC) Posts: 31 Location: Alberta		hi, just curious how to write ' inline evaluation of the function definitions - x:=2; f(x):=x^2=4; ' in SMath? I tried with no luck. my understanding is that on the same line you can define / evaluate multiple functions/variables. Also, I tried opening the one sheet I created with older version "1.0.8151.26392" and I get an error "variable and function name can't start with a number" Test.sm (36kb) downloaded 6 time(s).

That will resolve your problem. Actually sum() should be under line, don't know why. Probably function stop because of a different error. But reporting the wrong one (variable and function ...)

Just change your i definition to ii or something else, also add Clear(i). Or all i:=1 at sum()'s in function to something else, j:=1 for example. They are contradicting with each other. Regards

Rank: Advanced Member Groups: Registered Joined: 10/01/2017(UTC) Posts: 31 Location: Alberta		thanks overlord, actually adding the line to C(n) made it work, changing i to ii did not fix the problem. May I ask why different versions created this problem? and is it wrong to create this kind of function of a single line without adding an actual line? Lastly, is there a way to trace the error within a function as it runs (similar to F8 in VBA) to go step by step in calculations and see output of each line? Thanks alot.

Add Clear(i) to beginning of your function, it will work. I can only suggest you to use different and unique naming in your functions. That will prevent conflict of variables outside of function.

Originally Posted by: Mido0 ... and is it wrong to create this kind of function of a single line without adding an actual line? ... My guess is that the reason is that the counter variable of the sum is not local, and if it is defined, it can generate interference. That is why the best solution is to adopt as a good practice to do a Clear(n) for the sum counters. Examples about that here and here. Best regards. Alvaro.
