Witryna9 gru 2024 · To calculate MSE in MATLAB, you can use the “mse” function. This function takes in two arguments: the predicted values and the true values. The predicted values must be in the form of a column vector, and the true values must be in the form of a row vector. The function will return a scalar value representing the MSE.
