Function Documentation

fill_vector()

void fill_vector	(	std::istream &	istr,
		std::vector< double > &	v
	)

Fills the double-vector v with data from an input stream istr until this input stream ends regularily. The vector is cleared and its memory is automatically allocated.

Parameters

[in]	istr	input stream
[out]	v	C++ vector with double values

Warning

An exception is thrown in case of wrong data format or corrupted data.

read_vector_from_file()

void read_vector_from_file	(	const std::string &	file_name,
		std::vector< double > &	v
	)

This function opens the ASCII-file named file_name and reads the double data into the C++ vector v. If the file file_name does not exist then the code stops with an appropriate message.

Parameters

[in]	file_name	name of the ASCII-file
[out]	v	C++ vector with double values

write_vector_to_file()

void write_vector_to_file	(	const std::string &	file_name,
		const std::vector< double > &	v
	)

This function opens the ASCII-file named file_name and rewrites its with the double data from the C++ vector v. If there are problems in opening/generating file file_name then the code stops with an appropriate message.

Parameters

[in]	file_name	name of the ASCII-file
[in]	v	C++ vector with double values
