Hi, I was wondering how to create this gradient matrix without using a loop ? 1 1 1 1 1 1 4 4 4 4 1 4 9 9 9 1 4 9 16 16 1 4 9 16 25 I already have the main diagonal completed using the following x = 1 + cumsum(3:2:9) I don't know how to do the rest, any help would be great. Andy

Hi,

I was wondering how to create this gradient matrix without using a loop ?

I already have the main diagonal completed using the following

x = 1 + cumsum(3:2:9)

I don't know how to do the rest, any help would be great.

 a=cumsum(1:2:9);
 result=min(a,a.'),
