Fields| Name | Description | |
|---|---|---|
 | ColumnCount | (Inherited from MatrixStorageT) |
| ColumnIndices | An array containing the column indices of the non-zero values. Element "j" of the array is the number of the column in matrix that contains the j-th value in the Values array. |
| RowCount | (Inherited from MatrixStorageT) |
| RowPointers | The array containing the row indices of the existing rows. Element "i" of the array gives the index of the element in the Values array that is first non-zero element in a row "i". The last value is equal to ValueCount, so that the number of non-zero entries in row "i" is always given by RowPointers[i+i] - RowPointers[i]. This array thus has length RowCount+1. |
| Values | Array that contains the non-zero elements of matrix. Values of the non-zero elements of matrix are mapped into the values array using the row-major storage mapping described in a compressed sparse row (CSR) format. |
