[Numpy-discussion] Numpy newbie question: matrix creation

[Edmondo Porcu]

Dear all,

I am a Newbie with Numpy and I would need some advice on how to create a
matrix with certain characteristics :

 - Every entry should be minimum 0 maximum 1 with a step of 0.1 (legal
values are 0,0.1,0.2,0.3 etc)

- The number of columns of the matrix is a parameter of this matrix
creation algorithm

- Only the rows where the sum is 1 must be kept

Would great appreciate your advice and suggestions

Best Regards

Edmondo
