I don't see any option to do so with the fspecial() function. I looked at the information of highpass() on mathworks and I was confused about the inputs. So far I have this and it produces an error.
A = imread('landscape.jpg');
B = imresize(A, [256 256], 'Antialiasing', true);
E = highpass(1, pi/2);
G = imfilter(B, E);
imshow(G);

Hii,
For 'highpass' function the parameters to be passed should be normalised so highpass(0,0.5) won't be producing an error
