The arc hyperbolic sine of the elements of a vector vsAsinh, vdAsinh
Name vsAsinh, vdAsinh
The arc hyperbolic sine of the elements of a vector
Purpose vsAsinh and vdAsinh calculate the arc hyperbolic sine function of vector
elements:
y[i] = asinh(a[i]), for 0 <= i <= n-1
Usage VMATH:
#include <vmath.h>
void vsAsinh (int n, const float a[ ], float y [ ] ) ;
void vdAsinh (int n, const double a [ ], double y [ ] ) ;
VMATH8:
#include <vmath8.h>
void vsAsinh (long long n, const float a[ ], float y [ ] ) ;
void vdAsinh (long long n, const double a [ ], double y [ ] ) ;
Input n Number of elements to be calculated.
a Array of length at least n, specifying the input vector.
Output y Array of length at least n, specifying the output vector.
