Hi I have two sets of 281x281 data that have been normalised.And it is in percentage form.
Now, I would like to compare between two sets of data by looking at how many data in each sets exceeding threshold value? For eg; the threshold value is 10%
Thanks for your help

nnz(FirstMatrix > threshold)
nnz(SecondMatrix > threshold)
You might possibly also want
nnz(FirstMatirx > threshold & SecondMatrix > threshold)
