Enum Spectrum 

pub enum Spectrum<T = Time> {
    Real(Quantity<T>),
    Imaginary(Quantity<T>),
    Complex(Quantity<T>, Scalar),
    Mixed(Quantity<T>, Quantity<T>),
}

The fastest time scale of a right-hand side function, which bounds a stable time step.

The time scale is the reciprocal of the spectral radius of the Jacobian.

Variants

Real(Quantity<T>)

The eigenvalues are real and negative, as in diffusion.

Imaginary(Quantity<T>)

The eigenvalues are imaginary, as in waves.

Complex(Quantity<T>, Scalar)

The eigenvalues lie along a ray at the given angle from the negative real axis, as in damped waves, between $0$ (diffusion) and $\pi/2$ (waves).

Mixed(Quantity<T>, Quantity<T>)

The eigenvalues are real and negative at the first time scale and imaginary at the second, as in diffusion coupled to waves.
