pub fn quality(
cx: &mut Cx,
solve: &SteadySolve,
quantity_spec: &QuantitySpec,
wrt: Option<&[Symbol]>,
) -> FemmResult<QualityAnswer>Expand description
Returns the requested quantity and the certificate for a completed solve.
Passing Some(params) for wrt also computes a total finite-difference
gradient and annotates the returned certificate with its trust level.
Passing None skips gradient work.
