How to apply MCA(Morphological component analysis) for our map/image?

function [ im ] = rdmap_shs( fname )

figure()
x=csvread('120342_rdmap.csv');
ts=regexp('120342_rdmap.csv','\d*','match');
im=image(x);
colormap jet(90)
figname=strcat(erase('120342_rdmap.csv','.csv'),'.fig');
savefig(figname)

end

This is the code I used to make the map appear in a figure using a csvfile.

I want to try how to perform doing MCA for my map. I downloaded the code from gpeyre toolboxes

https://github.com/gpeyre/matlab-toolboxes/blob/master/toolbox_sparsity/perform_mca.m and I can't seem to make it work. Can anybody help?
