create a matrix from a matrix x=[-2 -1 0 1 2]; which follow quadratic equations

Hi everyone, i want to create a matrix from this matrix x=[-2 -1 0 1 2] in such a way that resultant matrix is [ (-2^2),(-2^1),(-2^0); (-1^2),(-1^1),(-1^0); (0^2),(0^1),(0^0); (1^2),(1^1),(1^0); (2^2),2^1),(2^0) ]

Answer 1

[Alexandra Harkai]

x = [-2:2];
y = [2:-1:0];
bsxfun(@power, x', y)

[Guillaume]

In 2016b, it's even simpler:

x.' .^ y

[Alexandra Harkai]

Very true.

thank you all

Answer 2

[Andrei Bobrov]

x = [-2 -1 0 1 2];
out = x(:).^(2:-1:0); % for R2016b
