What you have?
I have a raman spectra plot and I have to compare it with a reference spectra and find out the correlation betwen them or probablity of matching?
Read about corr2.
But the two matrixes here doesn't have the same number of datapoints.

Hi Ananya, as I understand you want to find out correlation coefficient between the two plots, and the matrices you have are also not of same size, you can use "interp", you can use the following link:
to find out the correlation coefficients you can use the following link for correlation:
