I continue to get the same issue although I have two matrices using only integers.
h1 = {-1, -2, -1; 0, 0, 0; 1, 2, 1};
ogI = imread('image.jpeg');
I = rgb2gray(ogI);
I1 = conv2(I, h1, 'same');
imshow(I1);
Even if I set 'I' to a single or double inside of the function it does not work. This may be trivial but anything would help, thank you.

You are defining h1 as a cell array. Define it as a numeric array
h1 = [-1, -2, -1; 0, 0, 0; 1, 2, 1]; % use square brackets
