Need Help on this. I would like to create a matrix of a random integer.
Example:
Currently, I am using "sample" function. This will create a matrix of integer but some integer values by row are similar.
3 2 4 1
4 1 3 2
1 3 1 3
2 4 2 4
Actually, I would like to generate this type of matrix:
3 2 4 1
4 1 3 2
1 3 2 4
2 4 1 3
Any idea of doing this. Really appreciate any help. Thanks.
However, there is no guarantee that two rows won't be identical, and there is also no guarantee that each column will also be a permutation. Do you have these constraints too?
