MATLAB Programming

5 Types of Functions
• From a function at any lower level. (Function C can call B or D, but not E.)
function A(x, y)
B(x, y);
D(y);
function B(x, y)
C(x);
D(y);
function C(x)
D(x);
end
end
function D(x)
E(x);
function E(x)
...
end
end
end
% Primary function
% Nested in A
% Nested in B
% Nested in A
% Nested in D
You can also call a subfunction from any nested function in the same M-file.
You can pass variable numbers of arguments to and from nested
functions, but you should be aware of how MATLAB interprets varargin,
varargout, nargin, andnargout under those circumstances. See "Passing
Optional Arguments to Nested Functions" in the MATLAB Programming
documentation for more information on this.
Note If you construct a function handle for a nested function, you can call the
nested function from any MATLAB function that has access to the handle.
See “Using Function Handles with Nested Functions” on page 5-21.
