Detailed Description

Row-wise representation of sparse double matrix.

The nonzeros of the matrix are stored in the arrays entryColumns and entryValues, each of length numNonzeros. The nonzeros of row r are stored at positions \( p \in \{a, a+1, \dotsc, b-2, b-1 \}\), where \( a := \) rowSlice[r] and \( b := \) rowSlice[r+1]. In particular, the length of the rowSlice array is numRows + 1. The column is entryColumns[ \( p \)] while the actual matrix entry is entryValues[ \( p \)].

The nonzeros of each row must be sorted by column in ascending order. Moreover, no duplicates are allowed and all stored entries must indeed be nonzero.
