static SparseMatrix* MathUtil::convertLinearConstraintCoefficientMatrixToTheOtherMajor	(	bool	isColumnMajor,
		int	startSize,
		int	valueSize,
		int *	start,
		int *	index,
		double *	value,
		int	dimension
	)			`[static]`

Parameters:

	isColumnMajor	holds whether the coefMatrix (AMatrix) holding linear program data is stored by column. If false, the matrix is stored by row.
	start	holds an integer array of start elements in coefMatrix (AMatrix), which points to the start of a column (row) of nonzero elements in coefMatrix (AMatrix).
	index	holds an integer array of rowIdx (or colIdx) elements in coefMatrix (AMatrix). If the matrix is stored by column (row), rowIdx (colIdx) is the array of row (column) indices.
	value	holds a double array of value elements in coefMatrix (AMatrix), which contains nonzero elements.
	dimension	holds the column count if the input matrix is row major (row count = start.length-1) or the row number if the input matrix is column major (columnh count = start.length -1)

Returns:: Linear constraint coefficient matrix in the other major of the input matrix. Return null if input matrix not valid.

std::string MathUtil::format_os_dtoa ( double x )

Parameters:

x

is the double that gets converted into a string this takes the David Gay dtoa and converts to a formatted string
