MATLAB Mean Square Error question

Would love some help on this MATLAB question. Thank you in advance.

Problem Summary following formula defines mean square error between two vector x, y: (1) ; x;) mse = n i=1 define a function called MSE that receives two matrices and calculate the mean square error of their elements your function should work with: two matrices with the same size one matrix and one scaler if just one input is provided by the user, you should calculate the variance of the matrix elements Code to call your function 1 2 y 3 MSE( [1 2 3 4; 5 6 7 8]). MSE( [1 2 3 4; 5 6 7 8], [1.1 2.1 3.1 4.2; 5.3 6.2 7.8 8.3]). MSE( [1 2 3 4; 5 6 7 8], 4) =
