GENERATE MATRIX FROM VECTORS

I want to generate a matrix M of TWO columns and J rows.

An initial value (=XSTART) is fixed for the first column

while the second column runs from a value

YSTART in increments K until a final value YEND .

Then an increment L is added to XSTART

and the second column runs again from

YSTART in increments K until a final value YEND.

The increment L stops if the value of X equals XEND.

For example, let

1) X runs in increment of 4 from 0 until 12 (XSTART=0, L=4, XEND=8)

The vector components are (0, 4, 8)

2) Y runs in increment of 5 from 0 until 15 (YSTART=0, K=5, YEND=15)

The vector components are (0, 5, 10, 15)

The resulting matrix should be

0 0

0 5

0 10

0 15

4 0

4 5

4 10

4 15

8 0

8 5

8 10

8 15

I hope someone know the correct syntax

and help me to write a command that generates

this matrix for given set of initial and end values

for x and y and their respective increments.

Thank you a lot

[Oleg Komarov]

x = 0:4:8;
y = 0:5:15;

numX = numel(x);
numY = numel(y);
y = repmat(y(:),numX,1);
x = repmat(x   ,numY,1);

out = [x(:) y]
