% @deftypefn {Function File} {[@var{img}, @var{map}, @var{alpha}] =} imread (@var{filename})
% Read images from various file formats.
%
% The size and numeric class of the output depends on the
% format of the image. A color image is returned as an
% MxNx3 matrix. Grey-level and black-and-white images are
% of size MxN.
% The color depth of the image determines the numeric
% class of the output: 'uint8' or 'uint16' for grey
% and color, and 'logical' for black and white.
