Struct IncgammaResidual

Source

pub struct IncgammaResidual {
    degrees: Vec<f64>,
    arguments: Vec<Complex>,
    size: usize,
}

Expand description

What incgamma_array saves for its pullback: the degrees and the arguments. Only the arguments get gradients.

Implementations§

Source §

impl IncgammaResidual

Source

pub fn new(degrees: Vec<f64>, arguments: Vec<Complex>) -> Result<Self>

Keep the broadcast inputs needed by derivatives without evaluating values.

Source

pub fn pushforward(&self, tangents: [&[Complex]; 1]) -> Result<Vec<Complex>>

Directional derivative with respect to the complex argument.

Source

pub fn pullback(&self, cotangent: &[Complex]) -> Result<Vec<Complex>>

The gradient with respect to the arguments, given the gradient cotangent with respect to the values: cotangent times the conjugate of dGamma/dz.
