img = imread('cameraman.jpg');
imshow(img);
img1 = imnoise(img,'salt & pepper', 0.02);   
figure,imshow(img1)
vet=fspecial('average');
vet1=filter2(vet,img1)

I got this error:

Attempt to execute SCRIPT rot90 as a function:
D:\MATLAB\homework\rot90.m
Error in filter2 (line 39)
stencil = rot90(b,2);
Error in filt (line 9)
vet1=filter2(vet,img1)

Can anyone help me in this regard? Thank you.

It looks like you wrote your own rot90 function and saved it as "D:\MATLAB\homework\rot90.m" but it looks like your filt.m program calls filter2() (a built in function) and that function calls rot90. I think it's getting confused as to which version of rot90 it should run. What does this say:

which -all rot90

Then rename your rot90.m to something different so that filter2 will call the built-in one from the Mathworks like it expects to.
