Function Documentation

EnsureAtUniformPrecision() [1/3]

unsigned bertini::tracking::adaptive::EnsureAtUniformPrecision ( TimeCont< complex_dbl > & , SampCont< complex_dbl > &  )

inline

Does not a thing, because cannot.

Cannot change precision of fixed precision hardware doubles. This function is provided for template lookup, and interface completeness; its arguments (some times and space samples ) are intentionally ignored.

Returns

The precision, which is now uniform.

EnsureAtUniformPrecision() [2/3]

unsigned bertini::tracking::adaptive::EnsureAtUniformPrecision ( TimeCont< complex_mp > & times, SampCont< complex_mp > & samples )

inline

Changes precision of complex_mp to highest needed precision for the samples.

Parameters

times	Some times .
samples	Some space samples .

Returns

The precision, which is now uniform.

EnsureAtUniformPrecision() [3/3]

unsigned bertini::tracking::adaptive::EnsureAtUniformPrecision ( TimeCont< complex_mp > & times, SampCont< complex_mp > & samples, SampCont< complex_mp > & derivatives )

inline

Changes precision of complex_mp to highest needed precision for the samples.

This function does NOT do any refinement, it merely changes the precision of default, and of the input objects.

Parameters

times	The times of some space samples
samples	Some spatial samples, probably obtained from an Endgame
derivatives	The derivatives of the space samples, at the time samples. Again, probably obtained from Endgame.

Returns

The precision changed to.

MaxPrecision() [1/2]

unsigned bertini::tracking::adaptive::MaxPrecision ( SampCont< complex_mp > const & samples )

inline

Get the maximum precision among an input set of space samples.

This is computed based on the first coordinate. Length-zero samples will cause either an assert or a throw (from Eigen, not Bertini2).

Parameters

samples

Some complex samples in space, obtained from tracking probably.

Returns

The maximum precision among those samples.

MaxPrecision() [2/2]

unsigned bertini::tracking::adaptive::MaxPrecision ( TimeCont< complex_mp > const & times )

inline

Gets the maximum precision among a set of times.

Parameters

times

Some complex times.

Returns

The maximum precision among those times.

SetPrecision() [1/2]

void bertini::tracking::adaptive::SetPrecision ( SampCont< complex_mp > & samples, unsigned prec )

inline

Sets the precision of each space sample to be of input precision.

Parameters

samples	The samples of which to change precision.
prec	The new precision the samples should have.

SetPrecision() [2/2]

void bertini::tracking::adaptive::SetPrecision ( TimeCont< complex_mp > & times, unsigned prec )

inline

Sets the precision of each time sample to be of input precision.

Parameters

times	The times of which to change precision.
prec	The new precision the times should have.
