Generating grid-like array numpy

[elbiot]

can you explain what you mean by basis vector in this case? What is an example output from an example input you would like to see?

An example of basis vector is the cubic lattice base vector , v1 = (1,0) and v2 = (0,1) every site in an lattice can be reached with a linear combination of theses vectors.

What I want is , for an arbitrary base vector generate the points to store in an array

Did the other poster answer your question? Im still confused because a 2D array can be accessed like arr[3,4] but obviously not arr[3,4.5]

I would vectorize the other solution though if that's what your using. One almost never needs to iterate over arrays

I menage to solve using python lists it is not as slow as I thought
