Function Documentation

void computeNumDenom	(	char **	numer,
		char **	denom,
		char *	s
	)

the computeNumdenom function is in the bertini library, but not the headers, hence its inclusion here. it takes in a character array, and pointers which return the numerator and denominator of the number. We pass the input by casting via (char *)

Parameters

s	the number to be converted to rational form

Returns

numer the numerator

denom the denomenator

int GetLastNumSent	(	boost::filesystem::path	base_dir,
		std::vector< int > &	lastnumsent,
		int	numprocs
	)

Deprecated. Gets the highest index set on a previous attempt at the run.

Parameters

base_dir	Directory in which to look for the lastnumsent0,1 files
lastnumsent	Mutable vector in which to place the lastnumsent info read in by this function
numprocs	Number of processors in this attempt.

int GetMcNumLines	(	boost::filesystem::path	base_dir,
		int	numparam
	)

Gets the number of lines in the mc file. essentially reads the top line of the file.

Parameters

base_dir	The directory in which to look for the mcfile.
numparam	Number of parameters in the problem. Deprecated?

Returns

terminationint - The number of parameter points in the file. Note that this could acceptably be smaller than the actual number, but not larger.

Here is the caller graph for this function:

int GetStart	(	boost::filesystem::path	dir,
		std::string &	start,
		std::string	startfilename
	)

reads in the start file to memory

Parameters

dir	The directory in which to read the start file
start	MUTABLE String containing the start file
startfilename	The name of the start file. This is a user-set name.

Here is the caller graph for this function:

void getTermination_OpenMC	(	std::ifstream &	mc_in_stream,
		std::ofstream &	mc_out_stream,
		int &	terminationint,
		std::vector< int > &	KVector,
		runinfo &	paramotopy_info,
		ProgSettings &	paramotopy_settings
	)

gets the number of points in the parameter set, and opens the mc_out_stream file (if applicable). for both the user-defined style and the computer-generated.

Parameters

mc_in_stream	MUTABLE the stream for reading parameter points in the case of user-defined parameter points.
mc_out_stream	MUTABLE the stream for WRITING parameter points in case of computer-generated points.
terminationint	MUTABLE the number of points in the solve
KVector	vector of indices, for conversion from an integer to an index vector.
paramotopy_info	the parsed input file.
paramotopy_settings	the bertini and paramotopy settings for the current run.

void ReadDotOut	(	std::vector< std::string > &	Numoutvector,
		std::vector< std::string > &	arroutvector,
		std::vector< std::string > &	degoutvector,
		std::vector< std::string > &	namesoutvector,
		std::vector< std::string > &	configvector,
		std::vector< std::string > &	funcinputvector,
		std::vector< std::string > &	preproc_datavector
	)

Reads in all .out files, into mutable vectors of strings. Assumes the process is working in the directory containing the files.

Parameters

Numoutvector	Stores the num.out file.
arroutvector	Stores the arr.out file.
degoutvector	Stores the deg.out file.
namesoutvector	Stores the names.out file.
configvector	Stores the config file.
funcinputvector	Stores the func_input file.
preproc_datavector	Store the preproc_data file.

void WriteDotOut	(	std::vector< std::string > &	arroutvector,
		std::vector< std::string > &	degoutvector,
		std::vector< std::string > &	namesoutvector,
		std::vector< std::string > &	configvector,
		std::vector< std::string > &	funcinputvector,
		std::vector< std::string > &	preproc_datavector
	)

Writes to disk the .out files, but not num.out. This function needs only be called once, and the process must be in the correct directory.

Parameters

arroutvector	Stores the arr.out file.
degoutvector	Stores the deg.out file.
namesoutvector	Stores the names.out file.
configvector	Stores the config file.
funcinputvector	Stores the func_input file.
preproc_datavector	Stores the preproc_data file.

void WriteNumDotOut	(	std::vector< std::string >	Numoutvector,
		std::vector< std::pair< double, double > >	AllParams,
		int	numparam,
		bool	standardstep2
	)

Writes the num.out file for the bertini solve. We overwrite the appropriate places of the original file with the current parameter values.

Parameters

Numoutvector	Stores the num.out file, as read in by ReadDotOut.
AllParams	The current parameter values.
numparam	The numbers of parameters in the problem.
standardstep2	Flag to indicate if a parameter continuation run is done * or if a default bertini run is done on multiple parameter points
