I have two matrices A and B both with same siez, i.e. 119*173.
What is the best way to find the correlation between those two?
I have tried couple of options, corr, corr2, corcoef etc.
It just gives a 2*2 NaN matrix, A and B have a lot of NaN's how to fix this

Can you also please be more clear about what you mean by the "correlation between two matrices"?
Do you expect one correlation coefficient, treating the matrices as 20,587x1 vectors that are simply shaped as 119x173?
Or do you expect 173 correlation coefficients -- one for each 119x1 column vector?
Or something else?

One possibility, which ignores any element for which A or B is NaN, is
corrcoef(A,B,'rows','complete')
