Correlation between two different matrices

Hi,

I have a matrix (attached as Ideal.jpg) and a smaller sized matrix that's a measurement of a subset of the ideal. The values in this measurement do not match the values in the ideal matrix, and it looks like a rotated subset.

Pls, how can I find and extract the section of the large matrix that best correlates with the smaller matrix? I want to find the difference between the matrices but need to know the best overlapping regions.

Thanks!

Hi,

In my opinion, the image processing can be a good possibility to find out how far they match by using, e.g.imread() and compare them sizewize and do small calcs of % match.

I'll try that, thanks.
