MATLAB Programming

Calling Functions
function varargout = byDiag(a)
varargout{1} = ' With VARARGOUT constructed by diagonal ...';
for k = -4:4
varargout{k + 6} = diag(a, k);
end
Call the function with five output variables. Again, MATLAB assigns
elements of varargout according to the manner in which it was constructed
within the function:
[text d1 d2 d3 d4] = byDiag(magic(5))
text =
With VARARGOUT constructed by diagonal ...
d1 =
11
d2 =
10
18
d3 =
4
12
25
d4 =
23
6
19

Calling External Functions
The MATLAB external interface offers a number of ways to run external
functions from MATLAB. This includes programs written in C or Fortran,
methods invoked on Java or COM (Component Object Model) objects,
functions that interface with serial port hardware, and functions stored in
shared libraries. The MATLAB External Interfaces documentation describes
these various interfaces and how to call these external functions.
