Hi, I see 2 implementations of sparse matrix in the math.commons.linear library.
1. OpenMapRealMatrix 2. SparseFieldMatrix Both are documented as "Sparse matrix implementation based on an open addressed map". Does anyone know what are the differences between the two? also, which method should I use to iterate only over the non zero elements? it seems that the WalkInRawOrder method runs over the entire row-length x col-length, the same as for RealMatrix. Thanks in advance! Raviv
