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)

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.

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.

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 >
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]
