Perform a complex Mobius transformation from (z,infz) to (w,infw) where the transformation coefficients are the standard aa,bb,cc,dd.
Infz is .TRUE. only when z is at complex infinity; likewise infw and w. For these infinite cases, it is important that numerical z==(0,0).
- Parameters
-
| [in] | aa | Mobius transformation complex coefficient |
| [in] | bb | Mobius transformation complex coefficient |
| [in] | cc | Mobius transformation complex coefficient |
| [in] | dd | Mobius transformation complex coefficient |
| [in] | z | complex input argument of the Mobius transformation |
| [in] | infz | logical indicator for z being a point at infinity |
| [out] | w | complex output of the Mobius transformation |
| [out] | infw | logical indicator for w being a point at infinity |
