Detailed Description

template<class T>
class vnl_matrix< T >

An ordinary mathematical matrix. The vnl_matrix<T> class implements two-dimensional arithmetic matrices for a user-specified numeric data type. Using the parameterized types facility of C++, it is possible, for example, for the user to create a matrix of rational numbers by parameterizing the vnl_matrix class over the Rational class. The only requirement for the type is that it supports the basic arithmetic operators.

Note: Unlike the other sequence classes, the vnl_matrix<T> class is fixed-size. It will not grow once the size has been specified to the constructor or changed by the assignment or multiplication operators. The vnl_matrix<T> class is row-based with addresses of rows being cached, and elements accessed as m[row][col].

Note: The matrix can, however, be resized using the resize(nr,nc) function.

Note: Indexing of the matrix is zero-based, so the top-left element is M(0,0).

Note: Inversion of matrix M, and other operations such as solving systems of linear equations are handled by the matrix decomposition classes in vnl/algo, such as matrix_inverse, svd, qr etc.

Note: Use a vnl_vector<T> with these matrices.
