MATLAB: How to define an array of symbolic functions

arrayfunctionMATLABsymbolic

I want to make an array a1(t) a2(t)… an(t).

syms a(t)

creates a symbolic parameter 't' and 'a' which is an unknown function of 't'. I want an array of just this. How do I do that? I want to use this array to solve a system of ODEs using dsolve.

In MATLAB it not possible to create an array of symbolic functions. If you have even one symbolic function then MATLAB will build a single function that returns an array.

I was looking at this the other day and noticed that diff(a1, x) would produce a function as output but that diff(a1(x), x) would produce an expression. I was wondering whether that made a difference for dsolve purposes and made a mental note to investigate but I did not get around to it yet.

MATLAB: Hello, I want to derive from a function such as (f=f0+Rf1+R^2f2+R^3f3) so that the answer is as follows: (f’=f0’+Rf1’+R^2f2’+R^3f3′)

syms f(x) f0(x) f1(x) f2(x) f3(x) R
fun=diff(f,x)==diff(f0,x)+R*diff(f1,x)+R^2*diff(f2,x)+R^3*diff(f3,x)
