Hi, I'm quite new to Matlab. im trying to write an encoded code to filter an image. i'm using the following filter code. filter = 1/9 * [1 1 1; 1 1 1; 1 1 1];
i get the message "matrix dimensions must agree", how would you go about filtering a whole image? do i have to loop it somehow? thanks

Use the filter2() or the conv2() command to apply the filter.
The mathematical operation that applies a filter is convolution, not matrix/vector multiplication.
