This API implements
$$y = \frac{x}{||x||_2}$$
This API divides each element in x by L2-norm and assigns the results to elements in y.
API signatures:
gscaleNorm2( N, x, strideX, y, strideY )
gscaleNorm2.ndarray( N, x, strideX, offsetX, y, strideY, offsetY )
where
N: number of indexed elements.x: input strided array.strideX: stride length for x.offsetX: starting index for x.y: output strided array.strideY: stride length for y.offsetY: starting index for y.
Notes
- To implement, call
blas/base/*nrm2, followed by blas/ext/base/*wax with alpha = 1 / nrm2(x).
Follow-on Work
Once completed and merged, the following packages can be added
