Detailed Description

Read-Only Sparse Matrix Iterator. Here is how to use the iterator to compute the sum of floating-point sparse matrix elements:

 SparseMatConstIterator it = m.begin(), it_end = m.end();
 double s = 0;
 CV_Assert( m.type() == CV_32F );
 for( ; it != it_end; ++it )
    s += it.value<float>();
