The function performs the operations in place; that is, the input and output complex arrays can be
the same.
Parameters
Input
arrayXReal
double-precision
array
Real part of x.
arrayXImaginary
double-precision
array
Imaginary part of x.
arrayYReal
double-precision
array
Real part of y.
arrayYImaginary
double-precision
array
Imaginary part of y.
numberofElements
integer Number of elements.
Output
outputArrayReal
double-precision
array
Real part of z.
outputArrayImaginary

Return
Value
status
integer Refer to error codes in
Table 3-2.
CxRecip
int status = CxRecip (double xReal, double xImaginary, double *outputReal,
double *outputImaginary);
Purpose
Finds the reciprocal of a complex number. The function obtains the resulting complex number
by using the following formulas.
yr = xr / (xr
2
+ xi
2
)
yi = -xi / (xr
2
+ xi
2
)
