BLAS Level 2 DGER for ndarrays

Usage

dger( alpha, A, x, y )

Performs the rank 1 operation A <- alpha * x * yT + A for scalar alpha, m element vector x, n element vector y and m x n element matrix A.

Result is overwritten in matrix A. All other inputs are unchanged.

Example

dger = require('ndarray-blas-dger')

A = ndarray([1,2,3,4,5,6], [2,2]),
x = ndarray([1,2]),
y = ndarray([3,4,5])

( -4, x, y, A );

esult: A =  -11.000  -22.000
            -13.000  -28.000
            -15.000  -34.000
