void
cublasZdscal (int n, double alpha, cuDoubleComplex *x, int incx)

replaces double-complex vector x with double-complex alpha * x. For i
= 0 to n - 1, it replaces x[ix + i * incx] with alpha * x[ix + i * incx],
where ix = 1 if incx >= 0, else ix = 1 + (1 - n) * incx.

Input
-----
n      number of elements in input vectors
alpha  double precision scalar multiplier
x      double-complex vector with n elements
incx   storage spacing between elements of x

Output
------
x      double-complex result (unchanged if n <= 0 or incx <= 0)

Error status for this function can be retrieved via cublasGetError().

Error Status
------------
CUBLAS_STATUS_NOT_INITIALIZED  if CUBLAS library has not been initialized
CUBLAS_STATUS_ARCH_MISMATCH    if invoked on device without DP support
CUBLAS_STATUS_EXECUTION_FAILED if function failed to launch on GPU
