Low-rank framework for multi-core CPUs and GPUs
|
| Common utilities | Common utility functions |
| Linear algebra | Dense matrix and vector operations used throughout the library |
| Dynamical low-rank (matrix) | Two-factor (i.e. matrix) low-rank decompositions and their corresponding operations |
| Dynamical low-rank (tensor) | Tensor low-rank representations and supporting tree and index operations |
| Interpolatory low-rank | Interpolation-based construction of low-rank representations |
| Fast Fourier transform | Batched Fourier transforms, commonly applying one transform per rank index |
