numpy.ogrid¶

numpy.ogrid = <numpy.lib.index_tricks.nd_grid object>¶

nd_grid instance which returns an open multi-dimensional “meshgrid”.

An instance ofnumpy.lib.index_tricks.nd_grid which returns an open(i.e. not fleshed out) mesh-grid when indexed, so that only one dimensionof each returned array is greater than 1. The dimension and number of theoutput arrays are equal to the number of indexing dimensions. If the steplength is not a complex number, then the stop is not inclusive.

However, if the step length is acomplex number (e.g. 5j), thenthe integer part of its magnitude is interpreted as specifying thenumber of points to create between the start and stop values, wherethe stop valueis inclusive.

Returns:	mesh-grid `ndarrays` with only one dimension :math:`neq 1`
