int Ifpack_AnalyzeMatrixElements | ( | const Epetra_RowMatrix & | A, |
const bool | abs = false , |
||
const int | steps = 10 |
||
) |
Analyzes the distribution of values of the input matrix A.
A | - (In) matrix to be analyzed. |
abs | - (In) if true , the function will analyze matrix B, whose elements are defined as \( B_{i,i} = | A_{i,i}| \). |
steps | - (In) number of intervals for the analysis. |
An example of output is reported Usage of Ifpack_AnalyzeMatrixElements().
