%
% Usage
%
% The meshgrid function generates arrays that can be used for the
% generation of surface plots. The syntax is one of
%
% [X,Y] = meshgrid(x)
% [X,Y] = meshgrid(x,y)
% [X,Y,Z] = meshgrid(x,y,z)
%
% where x,y,z are vectors, and X,Y,Z are matrices. In the first
% case [X,Y] = meshgrid(x), the rows of X and the columns of Y
% contain copies of the vector x. In the second case
% [X,Y] = meshgrid(x,y), the rows of X contain copies of x, and
% the columns of Y contain copies of y. In the third case, each
% input is copied along the row, column or slice direction of the
% corresponding output variable.
