4.21 vmlmish - MISH activation

#include <mvecml.h> 
 
void vmlmish (int n, double *restrict y, int incy, const double *restrict x, int incx); 
void vmlmishf(int n, float *restrict y, int incy, const float *restrict x, int incx); 
 
void vmlmish_64(long n, double *restrict y, long incy, const double *restrict x, long incx); 
void vmlmishf_64(long n, float *restrict y, long incy, const float *restrict x, long incx);

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

y=.tanh(log(ex+ 1))x

4.21.1 Parameters

N - INTEGER

ENTRY: Number of elements of x  and y  .
CONSTRAINT: n ≥1  .

Y - ARRAY OF REAL

EXIT: Result vector y  .
CONSTRAINT: Must contain n× incy  elements.
CONSTRAINT: Must not overlap with array x  .

INCY - INTEGER

ENTRY: Stride for the vector y  .
CONSTRAINT: incy̸= 0  .
BEHAVIOR: A negative stride will traverse the array in reverse.

X - ARRAY OF REAL

ENTRY: Input vector x  .
CONSTRAINT: Must contain n× incx  elements.
CONSTRAINT: Must not overlap with array y  .

INCX - INTEGER

ENTRY: Stride for the vector x  .
CONSTRAINT: incx̸= 0  .
BEHAVIOR: A negative stride will traverse the array in reverse.
