specular.calculation

Backend-aware specular differentiation and scaled angular means.

Function	Description
scaled_mean	Evaluate the scaled angular mean elementwise.
derivative	Differentiate a scalar-input, scalar- or vector-valued function.
gradient	Compute the specular gradient of a scalar-valued function.
jacobian	Compute the specular Jacobian of a vector-valued function.

These functions are also available directly as specular.scaled_mean, specular.derivative, specular.gradient, and specular.jacobian.

See Calculation in the User Guide for usage and finite-difference step selection, and specular.backends for backend selection.
