Construct an open mesh from multiple sequences.
LAX-backend implementation of
Original docstring below.
This function takes N 1-D sequences and returns N outputs with N dimensions each, such that the shape is 1 in all but one dimension and the dimension with the non-unit shape value cycles through all N dimensions.
Using ix_ one can quickly construct index arrays that will index the cross product.
a[np.ix_([1,3],[2,5])]returns the array
[[a[1,2] a[1,5]], [a[3,2] a[3,5]]].
args (1-D sequences) – Each sequence should be of integer or boolean type. Boolean sequences will be interpreted as boolean masks for the corresponding dimension (equivalent to passing in
out – N arrays with N dimensions each, with N the number of input sequences. Together these arrays form an open mesh.
- Return type
tuple of ndarrays
