Function Documentation

void tmath::inout::CBDraw	(	Matrix &	x,
		Matrix &	y,
		const std::string &	f,
		const int &	width = 512,
		const int &	height = 384,
		const std::string &	format = ""
	)

Write the contents of the matrix to a CBDraw file. CBDraw files must have the extension '.cb'.

Parameters:

	x	contains the abscissa and must be one-dimensional (one row or one columns)
	y	contains the ordinates.
	format	defines the labelling of the axes according to CBDraw conventions

void tmath::inout::CBDraw	(	Matrix &	m,
		const std::string &	f,
		const int &	width = 512,
		const int &	height = 384,
		const std::string &	format = ""
	)

Write the contents of the matrix to a CBDraw file. CBDraw files must have the extension '.cb'. The abscissa is generated from the indices

Parameters:

	m	contains the ordinates
	format	defines the labelling of the axes according to CBDraw conventions

void tmath::inout::Image	(	const Matrix &	m,
		const string &	f,
		const int &	posterize = 0
	)

Write the contents of the matrix to a PNG file.

Parameters:

	m	contains the matrix
	f	contains the file name
	posterize	control the number of different colors actually used. if posterize==0, then colors vary smoothly.

Matrix tmath::inout::MatrixInput

(

const string &

f

)

Reads a matrix from a text file or binary file. Binary files must have the extension '.bin'.

Parameters:

f

contains the file name

void tmath::inout::Output	(	const Matrix &	m,
		const string &	f
	)

Write the contents of the matrix to a text file ore binary file. Binary files must have the extension '.bin'.

Parameters:

	m	contains the matrix
	f	contains the file name
