Map

These are convenience functions returning Map objects. The Map() static functions return unaligned Map objects, while the AlignedMap() functions return aligned Map objects and thus should be called only with 16-byte-aligned data pointers.

Detailed Description

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

Dense storage base class for matrices and arrays.

This class can be extended with the help of the plugin mechanism described on the page TopicCustomizingEigen by defining the preprocessor symbol EIGEN_PLAINOBJECTBASE_PLUGIN.

EIGEN_STRONG_INLINE Derived& Eigen::PlainObjectBase< Derived >::_set ( const DenseBase< OtherDerived > &  other) [inline, protected]

Copies the value of the expression other into *this with automatic resizing.

*this might be resized to match the dimensions of other. If *this was a null matrix (not already initialized), it will be initialized.

Note that copying a row-vector into a vector (and conversely) is allowed. The resizing, if any, is then done in the appropriate way so that row-vectors remain row-vectors and vectors remain vectors.

EIGEN_STRONG_INLINE void Eigen::PlainObjectBase< Derived >::conservativeResize ( Index  nbRows,

) [inline]

Resizes the matrix to rows x cols while leaving old values untouched.

The method is intended for matrices of dynamic size. If you only want to change the number of rows and/or of columns, you can use conservativeResize(NoChange_t, Index) or conservativeResize(Index, NoChange_t).

Matrices are resized relative to the top-left element. In case values need to be appended to the matrix they will be uninitialized.

Definition at line 342 of file PlainObjectBase.h.

template<typename Derived>
EIGEN_STRONG_INLINE void Eigen::PlainObjectBase< Derived >::conservativeResize ( Index  nbRows,
NoChange_t   
) [inline]

Resizes the matrix to rows x cols while leaving old values untouched.

As opposed to conservativeResize(Index rows, Index cols), this version leaves the number of columns unchanged.

In case the matrix is growing, new rows will be uninitialized.

template<typename Derived>
EIGEN_STRONG_INLINE void Eigen::PlainObjectBase< Derived >::conservativeResize ( Index  size) [inline]

Resizes the vector to size while retaining old values.

. This method does not work for partially dynamic matrices when the static dimension is anything other than 1. For example it will not work with Matrix<double, 2, Dynamic>.

When values are appended, they will be uninitialized.

EIGEN_STRONG_INLINE Derived& Eigen::PlainObjectBase< Derived >::operator= ( const EigenBase< OtherDerived > &  other) [inline]

Copies the generic expression other into *this.

The expression must provide a (templated) evalTo(Derived& dst) const function which does the actual job. In practice, this allows any user to write its own special matrix without having to modify MatrixBase

Returns:
a reference to *this.

EIGEN_STRONG_INLINE void Eigen::PlainObjectBase< Derived >::resize ( Index  nbRows,
Index  nbCols 
) [inline]

Resizes *this to a rows x cols matrix.

This method is intended for dynamic-size matrices, although it is legal to call it on any matrix as long as fixed dimensions are left unchanged. If you only want to change the number of rows and/or of columns, you can use resize(NoChange_t, Index), resize(Index, NoChange_t).

If the current number of coefficients of *this exactly matches the product rows * cols, then no memory allocation is performed and the current values are left unchanged. In all other cases, including shrinking, the data is reallocated and all previous values are lost.

Example: 

 Output:

Resizes *this to a vector of length size 


. This method does not work for partially dynamic matrices when the static dimension is anything other than 1. For example it will not work with Matrix<double, 2, Dynamic>.

Resizes *this to have the same dimensions as other. Takes care of doing all the checking that's needed.


Note that copying a row-vector into a vector (and conversely) is allowed. The resizing, if any, is then done in the appropriate way so that row-vectors remain row-vectors and vectors remain vectors.
