initial commit to HG from
Changeset:
646 (e263d8a21543) added further path and more save "camirversion.m"

function h = montageKPM(arg)
% montageKPM is like the built-in montage, but assumes input is MxNxK or filenames

% Converts patches (y,x,i) into patches(y,x,1,i)
% Also, adds a black border aroudn them
