Web% Sum the Squared Image and divide by the number of elements % to get the Mean Squared Error. It will be a scalar (a single number). mse = sum (sum (squaredErrorImage)) / (rows * columns); % Calculate PSNR (Peak Signal to Noise Ratio) from the MSE according to the formula. PSNR = 10 * log10 ( 256^2 / mse); % Alert user of the answer. Web25 mei 2016 · I have a matrix A and a matrix B, with the same number of rows and a different number of columns. I need to calculate the correlation coefficient between each single columns of the matrix A and all the columns of the matrix B.
