Name	Type	Description
`n`		Specifies the number of elements to be calculated.
`a`	Fortran 77: DOUBLE PRECISION for `vzcis` , `vmzcis`Fortran 90: REAL , INTENT(IN) for `vccis` , `vmccis`Fortran 90: DOUBLE PRECISION , INTENT(IN) for `vzcis` , `vmzcis`	Array that specifies the input vector `a` .
`inca` , `incy`	INTEGER, INTENT(IN)	Specifies increments for the elements of `a` and `y` .
`mode`	INTEGER(KIND=8) , INTENT(IN)	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.

Name	Type	Description
`y`	Fortran 77: DOUBLE COMPLEX for `vzcis` , `vmzcis`Fortran 90: COMPLEX , INTENT(OUT) for `vccis` , `vmccis`Fortran 90: DOUBLE COMPLEX , INTENT(OUT) for `vzcis` , `vmzcis`	Array that specifies the output vector `y` .

The v?CIS function computes complex exponent of real vector elements (cosine and sine of real vector elements combined to complex value).

Notes:

raises INVALID exception when the argument is SNAN
raises INVALID exception and sets the VM Error Status to VML_STATUS_ERRDOM for x=+∞ , x=-∞
