Detailed Description

template<typename _Tp>
class cv::SparseMat_< _Tp >

Template sparse n-dimensional array class derived from SparseMat.

SparseMat_ is a thin wrapper on top of SparseMat created in the same way as Mat_ . It simplifies notation of some operations:

int sz[] = {10, 20, 30};
SparseMat_<double> M(3, sz);
...
M.ref(1, 2, 3) = M(4, 5, 6) + M(7, 8, 9);
