Hi nine
If you are looking for Root Mean Square you can simply use command "rms". for more information write the following command in Command windows.
doc rms

Use the mean function and the complex-conjugate-transpose operator ('):
Rz = mean(z(:)*z(:)');
and:
Rz = mean((z(:)-zbar)*(z(:)-zbar)');
The subscript colon ‘z(:)’ forces ‘z’ to be a column vector, so you will not get an error if you give it ‘z’ a a row vector.

If you have the Image Processing Toolbox, simply use the function immse(). It works for 1-D "images/signals, as well as 2D images.
