How to scale a batch of vectors in-place?

yecao — Sun, 08 Aug 2021 09:44:03 GMT

I learn from the MKL manual that we can scale a batch of group of vectors using cblas_daxpy_batch() function.

It is an out-of-place operation.

If I just want to scale a batch of vectors in-place, is there a way to replace using cblas_dscal() on by one?

in that case, you need to build your own function.
