swig/Lib/octave/octcomplex.swg
Xavier Delacour a3689a02fc Fixes to two bugs in Lib/octave/octcomplex.swg (by Karl Wette)
* replace PyObject with octave_value in the SWIG_AsVal(float) fragment

* modify %swig_fromcplx_conv to use the correct Octave constructor for
  double (Complex) and float (FloatComplex)

Also remove an unneeded %ifcplusplus (Octave wrapping code is always in C++).

Checked that %swig_cplxflt_convn now compiles correctly for single-precision
complex values, and that make check-octave-examples passes.

Defines the As/From conversors for double/float complex, you need to
provide complex Type, the Name you want to use in the conversors,
the complex Constructor method, and the Real and Imag complex
accesor methods.
See the std_complex.i and ccomplex.i for concrete examples.
