The question is not clear: "call a second function within the first function" - this sounds easy, but "use the output of the first function as input to the second function" is something completely different.
- The first part:
function y = fcn1(a, b);
c = function2(a);
y = a + c;
end
function c = fcn2(a)
c = cos(a);
end
The fcn2 can either be defined in an own M-file or contained in the M-file of fcn1. If it is used inside fcn1 only, you can use a nested function also. Please read https://www.mathworks.com/help/matlab/ref/function.html.
- The second part:
y = fcn1(a, b);
z = fcn2(y);
Perhaps you should edit your question and clarify it.
