I would like to be able to automate the creation of the system of equations for a plot.

For the example attached, the function b(c,x) is used to plot, with the matrix "a" as the input. Currently with this setup, I would have to input each row of the function individually into the system of equations for a plot.

I would like to be able to increase or decrease the size of matrix "a" without having to edit the input of the plot.

Any ideas on how I could do that???

Try so

plots1.sm (3 КиБ) скачан 47 раз(а).

That's great! For the application that I needed, it as a system of matrices instead of a system of equations, and for that case I used mat2sys1.

Thanks for the help, I have never used that function, so I don't think I would've come up with using it.

also the converse sys2mat(,)
also: sys2mat(|(mat2sys(Vifft)|)
also: sys2mat(fft(Y))

Ernesto,

That's what I meant in "also +++"
