Static Public Member Functions
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. Here is an example using strides: Matrix4i A; A << 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16; std::cout << Matrix2i::Map(&A(1, 1), Stride<8, 2>()) << std::endl; Output: See also class Map

Construct a row of column vector with fixed size from an arbitrary number of coefficients.

This constructor is for 1D array or vectors with more than 4 coefficients.

Warning

To construct a column (resp. row) vector of fixed length, the number of values passed to this constructor must match the the fixed number of rows (resp. columns) of *this.

EIGEN_DEVICE_FUNC constexpr EIGEN_STRONG_INLINE void Eigen::PlainObjectBase< Derived >::resize ( Index  rows, Index  cols  )

inlineconstexpr

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:

MatrixXd m(2, 3);
m << 1, 2, 3, 4, 5, 6;
cout << "here's the 2x3 matrix m:" << endl << m << endl;
cout << "let's resize m to 3x2. This is a conservative resizing because 2*3==3*2." << endl;
m.resize(3, 2);
cout << "here's the 3x2 matrix m:" << endl << m << endl;
cout << "now let's resize m to size 2x2. This is NOT a conservative resizing, so it becomes uninitialized:" << endl;
m.resize(2, 2);
cout << m << endl;

resize() [2/4]

template<typename Derived >

constexpr EIGEN_DEVICE_FUNC void Eigen::PlainObjectBase< Derived >::resize ( Index  rows, NoChange_t    )

Resizes the matrix, changing only the number of rows. For the parameter of type NoChange_t, just pass the special value NoChange as in the example below.

Example:

MatrixXd m(3, 4);
m.resize(5, NoChange);
cout << "m: " << m.rows() << " rows, " << m.cols() << " cols" << endl;

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.

setZero() [4/4]

template<typename Derived >

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE Derived & Eigen::PlainObjectBase< Derived >::setZero	(	NoChange_t	,
		Index	cols
	)

Resizes to the given size, changing only the number of columns, and sets all coefficients in this expression to zero. For the parameter of type NoChange_t, just pass the special value NoChange.
