How can I resolve the following error?

ref = imread('6.jpg'); imshow(ref) A = imnoise(ref,'salt & pepper', 0.02); imshow(A) err = immse(A, ref); fprintf('\n The mean-squared error is %0.4f\n', err);

::::::::::Error:::::::::

Undefined function 'immse' for input arguments of type 'uint8'. Error in main (line 17) err = immse(I, im); >>

ref=imread('test.jpg');  % Change the image Name
figure, imshow(ref), title('Input Image');
A=imnoise(ref,'salt & pepper', 0.02);
figure,imshow(A), title('InputImage with Noise'); 
err=immse(A,ref); 
fprintf('\n The mean-squared error is %0.4f\n',err);

Which Matlab version you are using?

This function imse(Mean Square Error) was introduced in 2014b onwards.
