Hello, I have two vectors x and y, both 601x1. I want to multiply them to form a matrix of 601x601, but the values inside the matrix have to be sqrt(x^2+y^2). How do I do this? Thanks.

x = rand(601,1) ;
y = rand(601,1) ;
iwant = sqrt(x.^2+y'.^2) ;
size(iwant)

D = sqrt(x.'.^2 + y.^2)

@Nikola Segedin: Which Matlab versionare you using? Since R2016b an "implicit expanding" is applied. For former versions:
D = sqrt(bsxfun(@plus, x.'.^2, y.^2))
