z=xy

[x,y]=meshgrid(-6:1:6)

z=x*y

Is not giving the function z=x*y, anybody come across this issues pls?

Answer 1

[Sean de Wolski]

perhaps you means an element-wise multiplication?

z = x.*y;

what you're doing above is a matrix multiplication from linear algebra.

my bad, ya it works thnx! :)

Answer 2

[Laura Proctor]

Or, you could use matrix multiplication with vectors:

x = -6:6;
z = x'*x
