4.13 vmlsilu - SiLU activation

subroutine vmlsilu (n, y, incy, x, incx);
subroutine vmlsiluf(n, y, incy, x, incx);

Given an input vector x  and a result vector y  this function computes the SiLU activation function of the values in the x  vector and stores the result in the y  vector.

y= --x--x
   1+ e
