Name	Type	Description
`n`	const MKL_INT	Specifies the number of elements to be calculated.
`a`	const _Float16* for `vhPow3o2` , `vmhPow3o2` const float* for `vsPow3o2` , `vmsPow3o2` const double* for `vdPow3o2` , `vmdPow3o2`	Pointers to arrays that contain 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.
