Detailed Description

A complex number.

A complex number is internally represented like cartesian coordinates, ie a+ib. If you want to use a polar representation, have a look to the following code :

{
   wxEcComplex a(r*cos(theta), r*sin(theta)), b, c;
   b.Re = r * cos(theta);
   b.Im = r * sin(theta);
   c.FromPolar(r, theta);
}

Constructor & Destructor Documentation

wxEcComplex::wxEcComplex ( )

inline

The default constructor with initialization to zero.

wxEcComplex::wxEcComplex ( double  real, double  imaginary  )

inline

The extended constructor.

Parameters

real	The real part.
imaginary	The imaginary part.

Member Function Documentation

double wxEcComplex::Argument ( )

inline

Returns the argument of the complex number.

Remarks

(0,0) will return 0 even if the value should be undefined.

wxString wxEcComplex::AsString ( bool  usePolarNotation = false )

inline

Displays the complex number as string.

Parameters

usePolarNotation

false will return a+ib, true will return r.e^ti

wxEcComplex wxEcComplex::Conjugate ( )

inline

Returns the complex conjugate of the complex number.

void wxEcComplex::FromPolar ( double  r, double  theta  )

inline

Sets the value of the complex number from a polar couple (r,theta).

double wxEcComplex::Modulus ( )

inline

Returns the absolute value of the complex number.

bool wxEcComplex::operator!= ( const wxEcComplex &  complex ) const

inline

Operator to compare two complex numbers. It checks if Re!=Re or Im!=Im.

wxEcComplex wxEcComplex::operator* ( const wxEcComplex &  complex ) const

inline

Operator to multiply two complex numbers.

wxEcComplex wxEcComplex::operator+ ( const wxEcComplex &  complex ) const

inline

Operator to sum two complex numbers.

wxEcComplex wxEcComplex::operator- ( const wxEcComplex &  complex ) const

inline

Operator to substract two complex numbers.

wxEcComplex wxEcComplex::operator/ ( const wxEcComplex &  complex ) const

inline

Operator to divide two complex numbers. Check against division by zero is not performed.

bool wxEcComplex::operator== ( const wxEcComplex &  complex ) const

inline

Operator to compare two complex numbers. It checks if Re==Re and Im==Im.

Member Data Documentation

double wxEcComplex::Im
