It's just what it sounds like, though if you have the Image processing Toolbox you can use the immse() function

meanSquaredError = immse(signal, referenceSignal);
fprintf('\n The mean-squared error is %0.4f\n', meanSquaredError);

If you don't have that, then subtract the two signals, square it, and take the mean. What is your reference signal that you're using?

Thank you for your answer ,I don not have images I have two signals ,primary signal and reference signal I applied adaptive filter on these signals and got fetal ECG , I want to calculate mse for fetal ecg signal.
