Hi there,

Lets say I have a Function: F(x,y)

Data: x = { x1,x2 … ,xn } y = { y1,y2 … ,yn }

How can I efficiently create the matrix M =

[ F(x1,y1) , F(x1,y2) , … , F(x1,yn);

F(x2,y1) , F(x2,y2) , … , F(x2,yn);
…
… 
F(xn,y1) , F(xn,y2) , … , F(xn,yn)];

x = [1,2,3];
y = [4,5,6];
F = @(X,Y) X .* Y.^2;
M = bsxfun(F,x,y')

It needs a transpose at the end or

M = bsxfun(F,x',y)
