Detailed Description

template<typename Scalar_, int Rows_, int Cols_, int Options_, int MaxRows_, int MaxCols_>
class Eigen::Matrix< Scalar_, Rows_, Cols_, Options_, MaxRows_, MaxCols_ >

The matrix class, also used for vectors and row-vectors.

The Matrix class is the work-horse for all dense (note) matrices and vectors within Eigen. Vectors are matrices with one column, and row-vectors are matrices with one row.

The Matrix class encompasses both fixed-size and dynamic-size objects (note).

The first three template parameters are required:

Template Parameters

Scalar_	Numeric type, e.g. float, double, int or std::complex<float>. User defined scalar types are supported as well (see here).
Rows_	Number of rows, or Dynamic
Cols_	Number of columns, or Dynamic

The remaining template parameters are optional – in most cases you don't have to worry about them.

Template Parameters

Options_	A combination of either RowMajor or ColMajor, and of either AutoAlign or DontAlign. The former controls storage order, and defaults to column-major. The latter controls alignment, which is required for vectorization. It defaults to aligning matrices except for fixed sizes that aren't a multiple of the packet size.
MaxRows_	Maximum number of rows. Defaults to Rows_ (note).
MaxCols_	Maximum number of columns. Defaults to Cols_ (note).

Eigen provides a number of typedefs covering the usual cases. Here are some examples:

• Matrix2d is a 2x2 square matrix of doubles (Matrix<double, 2, 2>)
• Vector4f is a vector of 4 floats (Matrix<float, 4, 1>)
• RowVector3i is a row-vector of 3 ints (Matrix<int, 1, 3>)

• MatrixXf is a dynamic-size matrix of floats (Matrix<float, Dynamic, Dynamic>)
• VectorXf is a dynamic-size vector of floats (Matrix<float, Dynamic, 1>)

• Matrix2Xf is a partially fixed-size (dynamic-size) matrix of floats (Matrix<float, 2, Dynamic>)
• MatrixX3d is a partially dynamic-size (fixed-size) matrix of double (Matrix<double, Dynamic, 3>)

See this page for a complete list of predefined Matrix and Vector typedefs.

You can access elements of vectors and matrices using normal subscripting:

Eigen::VectorXd v(10);
v[0] = 0.1;
v[1] = 0.2;
v(0) = 0.3;
v(1) = 0.4;
 
Eigen::MatrixXi m(10, 10);
m(0, 1) = 1;
m(0, 2) = 2;
m(0, 3) = 3;

This class can be extended with the help of the plugin mechanism described on the page Extending MatrixBase (and other classes) by defining the preprocessor symbol EIGEN_MATRIX_PLUGIN.

Some notes:

Dense versus sparse:

This Matrix class handles dense, not sparse matrices and vectors. For sparse matrices and vectors, see the Sparse module.

Dense matrices and vectors are plain usual arrays of coefficients. All the coefficients are stored, in an ordinary contiguous array. This is unlike Sparse matrices and vectors where the coefficients are stored as a list of nonzero coefficients.

Fixed-size versus dynamic-size:

Fixed-size means that the numbers of rows and columns are known at compile-time. In this case, Eigen allocates the array of coefficients as a fixed-size array, as a class member. This makes sense for very small matrices, typically up to 4x4, sometimes up to 16x16. Larger matrices should be declared as dynamic-size even if one happens to know their size at compile-time.

Dynamic-size means that the numbers of rows or columns are not necessarily known at compile-time. In this case they are runtime variables, and the array of coefficients is allocated dynamically on the heap.

Note that dense matrices, be they Fixed-size or Dynamic-size, do not expand dynamically in the sense of a std::map. If you want this behavior, see the Sparse module.

MaxRows_ and MaxCols_:

In most cases, one just leaves these parameters to the default values. These parameters mean the maximum size of rows and columns that the matrix may have. They are useful in cases when the exact numbers of rows and columns are not known at compile-time, but it is known at compile-time that they cannot exceed a certain value. This happens when taking dynamic-size blocks inside fixed-size matrices: in this case MaxRows_ and MaxCols_ are the dimensions of the original matrix, while Rows_ and Cols_ are Dynamic.

ABI and storage layout

The table below summarizes the ABI of some possible Matrix instances which is fixed thorough the lifetime of Eigen 3.

Matrix type	Equivalent C structure
Matrix<T,Dynamic,Dynamic>	struct { T *data; // with (size_t(data)%EIGEN_MAX_ALIGN_BYTES)==0 Eigen::Index rows, cols; };
Matrix<T,Dynamic,1> Matrix<T,1,Dynamic>	struct { T *data; // with (size_t(data)%EIGEN_MAX_ALIGN_BYTES)==0 Eigen::Index size; };
Matrix<T,Rows,Cols>	struct { T data[Rows*Cols]; // with (size_t(data)%A(Rows*Cols*sizeof(T)))==0 };
Matrix<T,Dynamic,Dynamic,0,MaxRows,MaxCols>	struct { T data[MaxRows*MaxCols]; // with (size_t(data)%A(MaxRows*MaxCols*sizeof(T)))==0 Eigen::Index rows, cols; };

Note that in this table Rows, Cols, MaxRows and MaxCols are all positive integers. A(S) is defined to the largest possible power-of-two smaller to EIGEN_MAX_STATIC_ALIGN_BYTES.

EIGEN_DEVICE_FUNC constexpr EIGEN_STRONG_INLINE Eigen::Matrix< Scalar_, Rows_, Cols_, Options_, MaxRows_, MaxCols_ >::Matrix ( )

constexprdefault

Default constructor.

For fixed-size matrices, does nothing.

For dynamic-size matrices, creates an empty matrix of size 0. Does not allocate any array. Such a matrix is called a null matrix. This constructor is the unique way to create null matrices: resizing a matrix to 0 is not supported.

constexpr EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE Eigen::Matrix< Scalar_, Rows_, Cols_, Options_, MaxRows_, MaxCols_ >::Matrix ( const std::initializer_list< std::initializer_list< Scalar >> &  list )

inlineexplicitconstexpr

Constructs a Matrix and initializes it from the coefficients given as initializer-lists grouped by row. \cpp11.

In the general case, the constructor takes a list of rows, each row being represented as a list of coefficients:

Example:

MatrixXd m{{1, 2, 3}, {4, 5, 6}};
cout << m << endl;

Output:

Each of the inner initializer lists must contain the exact same number of elements, otherwise an assertion is triggered.

In the case of a compile-time column vector, implicit transposition from a single row is allowed. Therefore VectorXd{{1,2,3,4,5}} is legal and the more verbose syntax RowVectorXd{{1},{2},{3},{4},{5}} can be avoided:

Example:

VectorXi v{{1, 2}};
cout << v << endl;

Output:

In the case of fixed-sized matrices, the initializer list sizes must exactly match the matrix sizes, and implicit transposition is allowed for compile-time vectors only.

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.

                                                                                                {

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.
