Complex class

A high-performance equivalent to C++ <complex>.

Represents a complex number with a real and an imaginary part, providing operations for complex arithmetic and magnitude extraction.

Constructors

Complex(num real, [num imag = 0.0])
Creates a standard complex number. If the imaginary part is not provided, it defaults to 0.0.
const
Complex.polar(num rho, num theta)
Creates a complex number from polar coordinates. rho is the magnitude, and theta is the phase angle in radians.
factory

Properties

hashCode → int
Returns a hash code based on both the real and imaginary parts.
no setteroverride
runtimeType → Type
A representation of the runtime type of the object.

Methods

abs() → double
Computes the magnitude (absolute value) of the complex number.
arg() → double
Computes the phase angle (argument) of the complex number in radians.
conj() → Complex
Returns the complex conjugate of the number (real - imag * i).
imag() → double
Returns the imaginary component of the complex number.
norm() → double
Computes the squared magnitude of the complex number.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
real() → double
Returns the real component of the complex number.
toString() → String
Returns a human-readable string in the form a + bi or a - bi.

Operators

operator *(Complex other) → Complex
Multiplies two complex numbers using the standard complex multiplication rule.
operator +(Complex other) → Complex
Adds two complex numbers component-wise.
operator -(Complex other) → Complex
Subtracts other from this complex number component-wise.
operator /(Complex other) → Complex
Divides this complex number by other.
operator ==(Object other) → bool
Returns true if both the real and imaginary parts are equal.
