Hello Radovan and all Collabs,

Here is one very useful tool. Works great but could not
automate the update of the graph. In this setup, Smath
does not accept new "S" from col(S,#).It must be plugged
by hand. Read more in the work sheet.
Thanks Radovan for your appreciation.

Hello Jean, and thank you ones more

I was using SMath build 5890 on Win 10 and opened your file. Here is the screenshot of the matrix S.

Strange thing happened with the marked element . Only this one was represented as a fraction. I could not get rid of it until I deleted the all region and represented the matrix S once again. Moreover, you could use S and single index in this case because SMath uses rowwise single index for matrices.

As usual, I do not know if someone could reproduce this, or even better to explain what could have happened here with that single element. Another peculiar thing is when you change the number of decimal places of the entire matrix, only the second element go nuts and for some higher number of decimal places some of the elements are decimal and some are fractions.

This is because of the feature of SMath Studio to detect when the number should be displayed as fraction or not. I see it was turned on by user manually (normally this option set to Default).

Thank you Andrey for the reply,

I must have been forgotten about this, and I think I was bumped into it before and got the answer here on the Forum some time ago (I think even by yourself), but at the moment still do not get the logic of this SMath feature and how does it work. But It still surprised me this time when I saw the matrix with some decimal and some fractions elements.

Best Regards,
Radovan

Thanks Radovan, Andrey for doctoring.
It seems Smath 5346 [maybe other versions] does not save
the "Fraction" options, at least missing many times.

Here is a repost
