Member Function Documentation

bool MBMesquite::InvTransBarrier::evaluate	(	const MsqMatrix< 2, 2 > &	T,
		double &	result,
		MsqError &	err
	)		[virtual]

Evaluate \(\mu(T)\).

Parameters:

T	2x2 relative measure matrix (typically A W^-1)
result	Output: value of function

Returns:

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

Reimplemented from MBMesquite::TMetric.

}

bool MBMesquite::InvTransBarrier::evaluate	(	const MsqMatrix< 3, 3 > &	T,
		double &	result,
		MsqError &	err
	)		[virtual]

Evaluate \(\mu(T)\).

Parameters:

T	3x3 relative measure matrix (typically A W^-1)
result	Output: value of function

Returns:

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