ramp.m

% ramp(size,dimension,varargin) :  mimics the dipimage ramp function. See its documentation.
% first argument can be a size vector (or [256 256] is assumed),
% dimension is the direction into which to generate the ramp,
% and third argument one of
% 'left','right','true','corner','freq','radfreq','math',
% 'mleft','mright','mtrue','mcorner','mfreq','mradfreq'
%
% the global variable use_ramp_cuda decides whether to generate a dip_image or a cuda dip_image.
