n*V(*)V ( alpha x y -- alpha*x(*)y )
Basic Linear Algebra Subroutines (BLAS) interface » BLAS interface matrix operations

Prev:	n*V(*)Vconj+M ( alpha x y A -- alpha*x(*)yconj+A )
Next:	n*V(*)Vconj ( alpha x y -- alpha*x(*)yconj )

Vocabulary
math.blas.matrices

Inputs

alpha	a number
x	a blas-vector-base
y	a blas-vector-base

Outputs

alpha*x(*)y

a blas-matrix-base

Word description
Calculate the outer product αx⊗y and return a freshly allocated matrix containing the result. The returned matrix's height will match the length of x, and its width will match the length of y. Corresponds to the xGER and xGERU routines in BLAS.
