attribute [BackwardDerivativeOf]¶
Description¶
[BackwardDerivativeOf(fn)] is the back-reference version of [BackwardDerivative(derivFn)]
When used to decorate a function, the decorated function is considered the backward-derivative implementation of the referenced function fn.
Apart from this, the semantics of the custom derivative are the same as for [BackwardDerivative(derivFn)]
