Input Parameters

Name	Type	Description
`n`	const MKL_INT	Specifies the number of elements to be calculated.
`a`	const _Float16* for `vhAsinh` , `vmhAsinh` const float* for `vsAsinh` , `vmsAsinh` const double* for `vdAsinh` , `vmdAsinh` const MKL_Complex8* for `vcAsinh` , `vmcAsinh` const MKL_Complex16* for `vzAsinh` , `vmzAsinh`	Pointer to an array that contains the input vector `a` .
`inca` , `incy`	const MKL_INT	Specifies increments for the elements of `a` and `y` .
`mode`	const MKL_INT64	Overrides global VM mode setting for this function call. See vmlSetMode (Sets a new mode for VM functions according to the mode parameter and stores the previous VM mode to oldmode.) for possible values and their description.
