rustml

Module rustml::ops_inplace [−] [src]

Provides scalar, vector, vector-vector, vector-matrix and matrix-matrix operations.

Most of the operations are optimized using the underlying BLAS implementation. For each function it is explicitly documented whether or not BLAS is used.

Examples

The following example adds two vectors using BLAS and stores the result in the first vector.

use rustml::*;

let mut a = [1.0, 2.0, 3.0, 4.0, 5.0, 6.0];
let b = [3.0, 6.0, 2.0, 3.0, 6.0, 9.0];
a.iadd(&b);
assert_eq!(a, [4.0, 8.0, 5.0, 7.0, 11.0, 15.0]);
