Outputs

varargout: Anything that can be an output of a function.

Examples

Simple output example:

function varargout = foo()
  varargout{1} = 10;  
  varargout{2} = 20;
  varargout{3} = 30;
  end

[a] = foo()

a = 10

Multiple return example:

function varargout = foo()
  varargout{1} = 'a';
  varargout{2} = 'b';
  varargout{3} = 'c';
  end

foo() % it should return the first element of varargout here
R = foo() % it should return the first element of varargout here
[R1, R2] = foo() % it returns 'a' in R1 and 'b' in R2 OK
[R1,R2, R3] = foo()  % it returns 'a' in R1 and 'b' in R2 OK and 'c' in R3 OK

ans = a
R = a
R1 = a
R2 = b
R1 = a
R2 = b
R3 = c
