You're looking for numpy.where() .

I am new to numpy ...
Supposing I have 2 vectors v1 and v2 and a value (constant) k.
I want to build a vector r with all values of v1 greater than k and the
others from v2.
I found 2 ways, but not sure if they are the best solution:
1.
r1=v1.copy()
r2=v2.copy()
r1[r1=k]=0
r=r1+r2
2.
r=v1*(v1>=k

You just pass an array of ints

The submatrix must share
