How to create a variable number of dimensions for mgrid-CodePudding

I would like to create a meshgrid of variable dimensions by specifying the dimensions with a variable i.e. specifying dim=2, rather than manually changing the expression as in the example below to set a 2D mesh grid.

How would I implement a wrapper function for this?

The problem stems from not being familiar with the syntax that mgrid uses (index_tricks).

import numpy as np

mgrid = np.mgrid[
                  -5:5:5j,
                  -5:5:5j,
                ]

Observed documentation for mgrid, but there seems to be no info on setting the number of dimensions with a variable.

CodePudding user response：

You can create a tuple containing the slice manually, and repeat it some number of times:

import numpy as np

num_dims = 2

mgrid = np.mgrid[(slice(-5, 5, 5j),) * num_dims]
