Detailed Description

template<typename Type = real>
class theoretica::phasor< Type >

Complex number in exponential form \(\rho e^{i \theta}\).

Member Function Documentation

operator+()

template<typename Type = real>

phasor theoretica::phasor< Type >::operator+ ( const phasor< Type > &  other ) const

inline

Add two phasors.

Note

This operation is particularly slow for phasors as opposed to complex numbers in algebraic form.

operator-()

template<typename Type = real>

phasor theoretica::phasor< Type >::operator- ( const phasor< Type > &  other ) const

inline

Subtract two phasors.

Note

This operation is particularly slow for phasors as opposed to complex numbers in algebraic form.
