Hi Gautam,
It's the link for calculating root mean square error from which you can calculate mean square error as the difference is just a root involved in one
And here is the link to calculate PSNR

Or try this if you want to calculate mse for a 2D array,
err_val = mean(mean((orig_matrix - est_matrix).^2));
But if you have 1d Array, you can use mean function only once, by the way if you call mean multiple times without having it's requirement, the result will be same, it will just waste your debugging time only.
