I am comparing two histogrmas using pdist function but it gives me error "??? Error using ==> pdist2 at 133 X and Y must have the same number of columns." so how to get equal number of columns in both histogrmas?

One histogram is colour image histogram and another is sketch image histogram formed of concatenation of several small histogram(i.e. histogram of each block),so how can I get comparison get done??? colour image histogram have 1024 columns and sketch image has 59 columns...

In that case, do not histogram the color image into 1024 bins: histogram it into 59 bins.

I want you to clear one thing as I noticed now though I changed bins to 59 but still number of columns in color image remains 1024 only I displayed it on command prompt.. so please let me know difference between columns and bins and how it affects histogram? Thanks
