I think I need a for loop,

I need a Variable like x to have 3 different values and matlab to calculate the whole code based on those 3 values simultaneously. then I need another variable to have 3 different values, so I will have 9 different answers based on that change. but I need matlab to give me a matrix as (9,1)..any helps?

[John D'Errico]

[x,y] = meshgrid(1:3,[2 3 5])

x = 3×3

1 2 3 1 2 3 1 2 3

y = 3×3

2 2 2 3 3 3 5 5 5

z = x+y

z = 3×3

3 4 5 4 5 6 6 7 8

If you need it as a 9x1 array, then just unroll the arrays into vectors.

z = z(:)

z = 9×1

3 4 6 4 5 7 5 6 8

Start to learn how to use MATLAB as it is designed to be used, instead of writing everything as a loop.
