Variable number of output arguments - function, MATLAB Programming

Variable number of output arguments:

The variable number of output arguments can also be identified. For illustration, the one input argument is passed to the below function typesize. The function always return a character identifying whether the input argument was a vector ('v'), scalar ('s'), or matrix ('m'). This is returned through the output argument arrtype. In addition, when the input argument was a vector the function returns the length of the vector, and when the input argument was a matrix the function returns the number of rows & columns of the matrix. The output argument varargout is used; and it is a cell array. Therefore, for a vector of length is returned through the varargout and for a matrix both the number of rows & columns are returned through the varargout.
