cupynumeric.outer#

cupynumeric.outer( a: ndarray, b: ndarray, out: ndarray | None = None, ) → ndarray#

Compute the outer product of two vectors.

Given two vectors, a = [a0, a1, ..., aM] and b = [b0, b1, ..., bN], the outer product is:

[[a0*b0  a0*b1 ... a0*bN ]
 [a1*b0    .
 [ ...          .
 [aM*b0            aM*bN ]]

Parameters:

a ((M,) array_like) – First input vector. Input is flattened if not already 1-dimensional.
b ((N,) array_like) – Second input vector. Input is flattened if not already 1-dimensional.
out ((M, N) ndarray, optional) – A location where the result is stored. If its dtype is not what would be expected from this operation, then the result will be (unsafely) cast to out.

Returns:

output – output[i, j] = a[i] * b[j] If out is given, then it is returned.

Return type:

(M, N) ndarray
