Table 3-2.
CxDiv
int status = CxDiv (double xReal, double xImaginary, double yReal, yImaginary,
double *outputReal, double *outputImaginary);
Purpose
Divides two complex numbers. The function obtains the resulting complex number by using the
following formulas.
zr = (xr*yr + xi*yi) / (yr
2
+ yi
2
)
zi = (xi*yr - xr*yi ) / (yr
2
+ yi
2
)
Parameters
Input
xReal
double-precision Real part of x.
xImaginary
double-precision Imaginary part of x.
yReal
double-precision Real part of y.
yImaginary
double-precision Imaginary part of y.
Output
outputReal
double-precision Real part of z.
outputImaginary
double-precision Imaginary part of z.
