Member Function Documentation

bool GradTestMetricAbs::evaluate	(	const MsqMatrix< 2, 2 > &	A,
		const MsqMatrix< 2, 2 > &	W,
		double &	result,
		MsqError &	err
	)		[inline, virtual]

Evaluate \(\mu(A,W)\).

Parameters:

A	2x2 active matrix
W	2x2 target matrix
result	Output: value of function

Returns:

false if function cannot be evaluated for given A and W (e.g. division by zero, etc.), true otherwise.

		const MsqMatrix< 3, 3 > &	W,
		double &	result,
		MsqError &	err
	)		[inline, virtual]

Evaluate \(\mu(A,W)\).

Parameters:

A	3x3 active matrix
W	3x3 target matrix
result	Output: value of function

Returns:

false if function cannot be evaluated for given A and W (e.g. division by zero, etc.), true otherwise.
