[ojAlgo-user] How to create matrices

[Anders P. <an...@op...>]

You have to be a member to post to the list, and the code you posted  
makes no sense to me.

Have you tried:

BasicMatrix tmpRandomBigMatrix = BigMatrix.FACTORY.buildRandom(int,  
int, RandomNumber);

There are many different random number implementations/distributions:
