A `routines` folder is created under `/numojo`. Functions covered by [this page](https://numpy.org/doc/stable/reference/routines.html) will be considered for implementation in this folder. -2. Sub-folders[^single] will be created under `/routines` for each topic [on this page](https://numpy.org/doc/stable/reference/routines.html). Examples include: - - `/creation` (Array creation routines) - - `/logic` (Logic functions) - - `/mathematics` (Mathematical functions) - - ... -3. In each sub-folder, functions are grouped by topics into single Mojo files. For example, in the `/mathematics` folder, the following files will be created [(as classified by NumPy on this page)](https://numpy.org/doc/stable/reference/routines.math.html): - - `trig.mojo` (Trigonometric functions) - - `hyperbolic.mojo` (Hyperbolic functions) - - `exp_log.mojo` (Exponents and logarithms) - - `other.mojo` (Other special functions) - - `arithmetic.mojo` (Arithmetic operations) - - ... -4. In each file, functions are sorted alphabetically. -5. The `__init__.mojo` files of parent folders import functions from their child modules explicitly, avoiding `import *` to prevent polluting the namespace. - -Additionally, a `science` folder is created under `/numojo`. It is similar to the `routines` folder but contains sub-packages for features present in `scipy`[^science]. For example: - -Users can access the functions either directly at the top level or via sub-packages. - -1. Most common functions can be called from the top level, e.g., `numojo.sort()`. -2. Advanced features (e.g., those listed as sub-packages in `numpy` or `scipy`) need to be called via their own namespaces. For example: - - Random array generators, e.g., `numojo.random.randint()`. - - Linear algebra, e.g., `numojo.linalg.solve()`. - - FFT, e.g., `numojo.fft()`. - - Ordinary differential equations. - - Optimizers, e.g., `numojo.optimize`. +✅ **Current Implementation Status:** + +NuMojo has successfully implemented the planned organizational structure with the following hierarchy: + +### Core Infrastructure (`/numojo/core/`) +- **Data Types:** `NDArray`, `ComplexNDArray`, `Matrix` with full operator support +- **Shape/Strides:** Efficient memory layout handling (`ndshape.mojo`, `ndstrides.mojo`) +- **Memory Management:** `own_data.mojo`, `ref_data.mojo` for flexible memory handling +- **Complex Numbers:** Dedicated complex array support with full arithmetic +- **Traits:** Array-like interfaces and backend abstractions +- **Utilities:** Helper functions for array operations + +### Routines (`/numojo/routines/`) +Functions are organized by topic following NumPy's structure: + +1. **Array Creation** (`creation.mojo`): `arange`, `linspace`, `zeros`, `ones`, `full`, `eye`, etc. +2. **Mathematical Functions** (`/math/`): + -
