Let say there is matrix from meshgrid X,Y.
How to multiply it through a vector L in building third dimension of a F matrix ?
Each component of L(k) will miltiply X for example for the third dimension.
x = 0:1:5; y = 0:2:40
L = 1:0.1:10; % third dimension
[X, Y] = meshgrid(x,y);
F = (X.*Y).*L % problematic
F is two dimensions in X,Y and third dimention in L
And I would like how to access rows and colums and depth for this matrix ?

F = (X.*Y) .* reshape(L, 1, 1, [])
