typename ValueType = default_precision>
class gko::matrix::Diagonal< ValueType >
This class is a utility which efficiently implements the diagonal matrix (a linear operator which scales a vector row wise).
Objects of the Diagonal class always represent a square matrix, and require one array to store their values.
- Template Parameters
-
ValueType | precision of matrix elements |
IndexType | precision of matrix indexes of a CSR matrix the diagonal is applied or converted to. |
