Name	Type	Description
`n`	const MKL_INT	Specifies the number of elements to be calculated.
`a`	const _Float16* for `vhLog10` , `vmhLog10` const float* for `vsLog10` , `vmsLog10` const double* for `vdLog10` , `vmdLog10` const MKL_Complex8* for `vcLog10` , `vmcLog10` const MKL_Complex16* for `vzLog10` , `vmzLog10`	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.
