Detailed Description

template<typename Derived>
class Eigen::FloatMatrixFormatter< Derived >

Formatter for Eigen matrix type.

I want make it formatting any types of eigen

Template Parameters

Derived : MatrixBase's type which specify the matrix as vector, matrix with any storage type

Todo:: specialise the formatting; now it just support the float type only.

Constructor & Destructor Documentation

template<typename Derived >

Eigen::FloatMatrixFormatter< Derived >::FloatMatrixFormatter	(	const int &	w = `-1`,
		const unsigned int &	p = `2`
	)

inline

Default constructor.

Initialises the format tags for width, and precision.

Parameters

w	: width (default - no width constraints)
p	: the number of decimal places of precision (default - 4)

Definition at line 73 of file eigen/formatters.hpp.

Member Function Documentation

template<typename Derived >

FloatMatrixFormatter< Derived >& Eigen::FloatMatrixFormatter< Derived >::operator() ( const Derived & matrix )

inline

Format a matrix with permanently stored precision/width.

This function directly formats the specified input value with the stored settings.

Vector2d v; v << 1.0, 2.0;
Format<Vector2d> format;
cout << format(v) << endl;

Parameters

matrix : the matrix to be formatted (gets temporarily stored as a pointer).

Returns: FloatMatrixFormatter& : this formatter readied for use with a stream.

Definition at line 140 of file eigen/formatters.hpp.

template<typename Derived >

FloatMatrixFormatter< Derived >& Eigen::FloatMatrixFormatter< Derived >::operator()	(	const Derived &	matrix,
		const int &	w,
		const unsigned int &	p
	)

inline

Format a matrix with temporarily specified precision/width.

This function directly formats the specified input value and temporary settings.

Vector2d v; v << 1.0, 2.0;
Format<Vector2d> format;
cout << format(v,3,-1) << endl; // precision of 3 and no width constraint

Parameters

matrix	: the matrix to be formatted (gets temporarily stored as a pointer).
w	: the width to use for inserted floats (-1 is no width constraint).
p	: the number of decimal places of precision.

Returns: FloatMatrixFormatter& : this formatter readied for use with a stream.

Definition at line 162 of file eigen/formatters.hpp.

template<typename Derived >

FloatMatrixFormatter<Derived>& Eigen::FloatMatrixFormatter< Derived >::precision ( const unsigned int & p )

inline

Sets the precision format parameter.

Parameters

p	: the number of decimal places of precision.

Returns: FloatMatrixFormatter& : this formatter readied for use with a stream.

Definition at line 94 of file eigen/formatters.hpp.

template<typename Derived >

unsigned int Eigen::FloatMatrixFormatter< Derived >::precision ( )

inline

Returns the current precision setting.

Returns: unsigned int : the precision value.

Definition at line 116 of file eigen/formatters.hpp.

template<typename Derived >

FloatMatrixFormatter<Derived>& Eigen::FloatMatrixFormatter< Derived >::width ( const int & w )

inline

Sets the width format parameter.

Parameters

w	: the width to use for inserted floats (-1 is no width constraint).

Returns: FloatMatrixFormatter& : this formatter readied for use with a stream.

Definition at line 107 of file eigen/formatters.hpp.

template<typename Derived >

int Eigen::FloatMatrixFormatter< Derived >::width ( )

inline

Returns the current width setting.

Returns: int : the witdh value (-1 for no width constraint).

Definition at line 122 of file eigen/formatters.hpp.

template<typename Derived >

template<typename OutputStream , typename Derived_ >

ecl::Format<typename Derived::Scalar> Eigen::FloatMatrixFormatter< Derived >::format

private

Stream the formatter.

Insertion operator for sending the formatter to an output stream.

Parameters

ostream	: the output stream.
formatter	: the formatter to be inserted.

Template Parameters

OutputStream	: the type of the output stream to be inserted into.
Derived	: matrix type.

Returns: OutputStream : continue streaming with the updated output stream.

Exceptions

StandardException : throws if the formatter has un-specified _matrix [debug mode only]
