I have the following program:
x=linspace(0.1,0.3,3);
y=linspace(1,3,3);
[x1,y1] = meshgrid(x,y);
z=x1.*y1;
Now I want to rearrange the data to get a three column matrix C like this
0.1 1 z1
0.1 2 z2
0.1 3 z3
0.2 1 z4
0.2 2 z5
0.2 3 z6
0.3 1 z7
0.3 2 z8
0.3 3 z9
where z1 to z9 are the corresponding values. So, how to obtain the above matrix?

Add one line:
x=linspace(0.1,0.3,3);
y=linspace(1,3,3);
[x1,y1] = meshgrid(x,y);
z=x1.*y1;
C = [x1(:), y1(:), z(:)]
to produce:
C =
0.1 1 0.1
0.1 2 0.2
0.1 3 0.3
0.2 1 0.2
0.2 2 0.4
0.2 3 0.6
0.3 1 0.3
0.3 2 0.6
0.3 3 0.9
The ‘(:)’ subscripting convention forces a column vector.
