Detailed Description

template<typename MATRIXTYPE, size_t NR, size_t NC>
class mrpt::math::CSubmatrixView< MATRIXTYPE, NR, NC >

A wrapper around an existing matrix (of any kind) that allows operating on a subrange of the elements.

Example of usage:

  CMatrixDouble  C(10,10);
  CSubmatrixView<CMatrixDouble,3,2>  Csub(C,5,6);  // Csub is C([5,6,7],[6,7])
