Public Enumeration ConjugateGradientCode

Members

Member name	Value	Description
Success	0	Success.
StepSize	1	Invalid step size.
DescentNotObtained	-2	Descent direction was not obtained.
RoundingErrors	6	Rounding errors prevent further progress. There may not be a step which satisfies the sufficient decrease and curvature conditions. Tolerances may be too small.
StepHigh	5	The step size has reached the upper bound.
StepLow	4	The step size has reached the lower bound.
MaximumEvaluations	3	Maximum number of function evaluations has been reached.
Precision	2	Relative width of the interval of uncertainty is at machine precision.
