Question

I want to define a function like this:

function f = f1(fun,a,b,c)
f = c*fun(a+b);

Here fun is some function that I will pass when I use the function f.
How can I do this in Matlab?

Answer 1

Have you tried it? The best way to learn a tool like matlab is to try things!

In fact, you don’t even need to create an m-file function. I’ll do it using a function handle here.

fun = @(x) sin(x);
f1 = @(f,a,b,c) c*f(a+b);
f1(fun,2,3,4)

ans =
      -3.8357

I could have defined f1 as an m-file function too, but that would have required I save a file. Why bother?
