I am suganya doing a project on 'dct based iris recognition'.In our matlab program,we finished obtaining eye image,extracting the iris,applied dct,converted to binary and obtained the trained images.But on comparing the binary values of the training and testing images they are not matching...

I got error in line 42 =fileattrib(savefile); in createiristemplate.m. I'm using MATLAB 7.1. I also don't understand these code: savefile = ; =fileattrib(savefile); Is 'houghpara.mat' an attrib? anyone can help me to understand, what does this code segment is done?
