    %CUMPROD Cumulative product of elements.
%   Y = CUMPROD(X) computes the cumulative product along the first non-singleton
%   dimension of X. Y is the same size as X.
%
%   Y = CUMPROD(X,DIM) cumulates along the dimension specified by DIM.
% 
%   Y = CUMPROD(___,DIRECTION) cumulates in the direction specified by
%   DIRECTION using any of the above syntaxes:
%     'forward' - (default) uses the forward direction, from beginning to end.
%     'reverse' -           uses the reverse direction, from end to beginning.
%
%   Example: 
%       X = [0 1 2; 3 4 5]
%       cumprod(X,1)
%       cumprod(X,2)
%       cumprod(X,1,'reverse')
%       cumprod(X,2,'reverse')
