mrpt::math::CMatrixFixedNumeric< T, NROWS, NCOLS > Class Template Reference

Detailed Description

template<typename T, size_t NROWS, size_t NCOLS>
class mrpt::math::CMatrixFixedNumeric< T, NROWS, NCOLS >

A numeric matrix of compile-time fixed size.

Basically, this class is a wrapper on Eigen::Matrix<T,NROWS,NCOLS>, but with a RowMajor element memory layout (except for column vectors).

These matrices also have iterators to access all the elements in the matrix as a sequence, starting from the element (0,0), then row by row, from left to right.

Note

This class exists for backward compatibility of ancient times when MRPT didn't rely on Eigen, feel free to directly use Eigen::Matrix<> types instead.
