pdist custom distance function.

I have to use this distance in the pdist function:

norm((log(cov_1) - log(cov_2)),'fro')

I have already read the pdist documentation but I have not figured out how to define and call my distance in pdist.

someone could help, maybe with an example.

distfun = @(cov_1, cov_2) norm((log(cov_1) - log(cov_2)),'fro');

pdist(YourData, distfun)
