Member Function Documentation
| T2DMatrixVis& max_size_ratio | ( | const double | r) |
set maximal allowed ratio of block size compared to largest block size (default: 1000); if ratio is exceeded, block will not be printed to limit file size for very large matrices
| T2DMatrixVis& svd_ref | ( | const double | ref_max, |
| const double | ref_min = Limits::epsilon< double >() |
||
| ) |
set value of largest/smallest singular value to compare with for each block;
- if ref_max/ref_min ≤ 0, the largest/smallest local singular values per block are used
- good choice for ref_max is ∥A∥₂
