how differentiate symbolic function has a variable name matlab

Question

please,

I want matlab to generate dynamic variable name as many as specified number ex, generate F1,F2,...

but the problem that I want to differienate the unspeceified number I use

for k = 1:number

   eval(diff(['F', num2str(k)]))

end

so what's wrong?

Answer 1

You should start your code with:

f=sym('f',[1,number])

this creates symbolic variables f1... organised in an array.

for k = 1:number

   diff(f(k))

end

Avoid eval whenever possible. For reasons read doc eval.
