How do i get the Full Width Half Maximum (FWHM) from a matrix with 2 collumns and n-rows?

I have found a function that gives the FWHM if you define a function as "function width = fwhm(x,y)". But i simply have the pixel number in my first collumn, and the pixel value in the second collumn. How can i get the FWHM of this nx2 matrix?

wHM=fwhm(PaData(:,1),PaData(:,2));

I have the same problem here. Have you found out how to solve it?
