Function Documentation

CheckConsistency()

bool CheckConsistency	(	const std::vector< std::vector< double > > &	m,
		int	rows,
		int	cols )

Checks the consistency of the system of equations.

Parameters

m	The matrix representing the system.
rows	Number of rows in the matrix.
cols	Number of columns in the matrix.

Returns

true If the system is consistent.

false If the system is inconsistent.

DisplaySolution()

void DisplaySolution

(

const std::vector< double > &

solution

)

Displays the unique solution.

Parameters

solution

The solution vector.

InitMatrix()

bool InitMatrix	(	std::vector< std::vector< double > > &	m,
		const std::string &	filename,
		int &	rows,
		int &	cols )

Initializes the matrix by reading from a .in file.

Parameters

m	Reference to the matrix to be initialized.
filename	Name of the input file.
rows	Reference to store the number of rows.
cols	Reference to store the number of columns.

Returns

true If the matrix was successfully initialized.

false If there was an error during initialization.

ShowEquations()

void ShowEquations	(	const std::vector< std::vector< double > > &	m,
		int	rows,
		int	cols )

Displays the system of linear equations.

Parameters

m	The matrix representing the system.
rows	Number of equations.
cols	Number of variables plus one (for constants).
