NUMC - A Numerical Computing Library for C

Just like NumPy, but in C. This library is still in development, and is not yet ready for use.

Goals

• Create a library that is as easy (as possible) to use as NumPy
• Basic building blocks
  • Creation of arrays of any shape, type, and size
  • Loading and saving arrays to disk
  • Basic array manipulation: reshaping, transposing, copying, concatenating, etc.
  • Indexing and slicing
  • Basic arithmetic operations: addition, subtraction, multiplication, division, etc.
• Linear algebra
  • Matrix multiplication
  • Matrix inversion
  • Matrix decomposition
  • Eigenvalues and eigenvectors
  • Singular value decomposition
  • QR decomposition
  • Cholesky decomposition
  • LU decomposition
  • Solving linear systems
  • Solving eigenvalue problems

More goals will be added as development continues.

Showcase

As this library is intended to be a NumPy-like library, some of the functionality has been mimicked. Here is an example:

// Create a 2x3x4 array of integers full of zeros
NCarray numc_arr = nc_zeros(NC_INT, 3, 2, 3, 4);

// Print the array
nc_show(numc_arr);

NCarray([[[0, 0, 0, 0],
          [0, 0, 0, 0],
          [0, 0, 0, 0]],

         [[0, 0, 0, 0],
          [0, 0, 0, 0],
          [0, 0, 0, 0]]], type=i32)


// Reshape the array to be 6x4
numc_arr = nc_reshape(numc_arr, 2, 6, 4);

// Print the array
nc_show(numc_arr);

NCarray([[0, 0, 0, 0],
         [0, 0, 0, 0],
         [0, 0, 0, 0],
         [0, 0, 0, 0],
         [0, 0, 0, 0],
         [0, 0, 0, 0]], type=i32)

More examples can be found in the examples directory. //TODO: Add more examples. None exist yet. 😄

Contributing

This library is far from being finished, and your contributions are welcome. Of course, please open an issue first for a discussion.
