Struct Var
Source pub struct Var {
pub value: f64,
}
Expand description
A reverse-mode AD variable tracked on a computation tape.
Arithmetic operations on Var automatically record themselves on the
shared tape. After computation, use Tape::gradient to differentiate.
Create a constant (not differentiated) on the same tape as self.
ln(self) (natural logarithm)
self^n (power with another Var)
self^n (power with f64 constant)
