# Asin

Computes inverse sine of vector elements.

## Syntax

Fortran:

call vsasin( n, a, y )

call vdasin( n, a, y )

call vcasin( n, a, y )

call vzasin( n, a, y )

C:

vsAsin( n, a, y );

vdAsin( n, a, y );

vcAsin( n, a, y );

vzAsin( n, a, y );

## Input Parameters

Name | Type | Description
--- | --- | ---
n | FORTRAN: INTEGER, INTENT(IN) C: int | Specifies the number of elements to be calculated.
a | FORTRAN: REAL, INTENT(IN) for vsasin DOUBLE PRECISION, INTENT(IN) for vdasin COMPLEX, INTENT(IN) for vcasin DOUBLE COMPLEX, INTENT(IN) for vzasin C: const float* for vsAsin const double* for vdAsin const MKL_Complex8* for vcAsin const MKL_Complex16* for vzAsin | FORTRAN: Array, specifies the input vector a. C: Pointer to an array that contains the input vector a.
