Hello Gurus,
I need to do the following and was wondering if any of you knew an efficient way to do so.
I have 'n' matrices, each with different row size ('k_n') but same
number of columns (3). I need to get a matrix (p) with all possible combination of the rows.
Just to elaborate, I did the following by brute force;
>> n1
n1 =
7 0 1
>> n2
n2 =
2 0 1
2 0 2
>> n3
n3 =
3 0 1
3 0 2
3 0 3
3 0 4
p =
7 0 1 2 0 1 3 0 1
7 0 1 2 0 1 3 0 2
7 0 1 2 0 1 3 0 3
7 0 1 2 0 1 3 0 4
7 0 1 2 0 2 3 0 1
7 0 1 2 0 2 3 0 2
7 0 1 2 0 2 3 0 3
7 0 1 2 0 2 3 0 4
I highly appreciate your help. Thank you very much.
