nd_grid instance which returns an open multi-dimensional “meshgrid”.
An instance of numpy.lib.index_tricks.nd_grid which returns an open
(i.e. not fleshed out) mesh-grid when indexed, so that only one dimension
of each returned array is greater than 1. The dimension and number of the
output arrays are equal to the number of indexing dimensions. If the step
length is not a complex number, then the stop is not inclusive.
However, if the step length is a complex number (e.g. 5j), then
the integer part of its magnitude is interpreted as specifying the
number of points to create between the start and stop values, where
the stop value is inclusive.
ndarrays with only one dimension not equal to 1
class of ogrid and mgrid objects
like ogrid but returns dense (or fleshed out) mesh grids
>>> from numpy import ogrid
array([-1. , -0.5, 0. , 0.5, 1. ])
]), array([[0, 1, 2, 3, 4]])]
