%
% Usage
%
% Returns the number of elements in an array x, or in a subindex
% expression. The syntax for its use is either
%
% y = numel(x)
%
% or
%
% y = numel(x,varargin)
%
% Generally, numel returns prod(size(x)), the number of total
% elements in x. However, you can specify a number of indexing
% expressions for varagin such as index1, index2, ..., indexm.
% In that case, the output of numel is
% prod(size(x(index1,...,indexm))).

if (nargin==1)

for k=1:length(varargin)
len = len * numel(varargin{k});
