| Namespace | Purpose |
|---|---|
| dnp | Mathematical functions operating on scalars or arrays of data |
| dat | Data manipulation functions, treating the array as a matrix or retrieving statistics |
| dnp | Mathematical functions operating on scalars or arrays of data |
| func | Function fitting functions |
| im | Image processing functions |
| lz | Lazy evaluation functions |
