MDArray is a multidimensional array type for Swift. You can use it to represent vectors, matrices, and other higher order objects. It conforms to the MutableCollection protocol, and its math functions use the Accelerate framework.

Why use it?

You can use MDArray to store any type in the form of a multidimensional array, such as String values in the title banner above. Some of the more interesting applications include machine learning, signal processing, physics, engineering, and just good ol' mathematics.

Adding it to your project

Clone the repository using your terminal of choice, and add the appropriate files to your project.

https://github.com/colinc86/MDArray.git

The MDArray type and associated functions are separated in to different files. Depending on how you'll be using MDArray, you may only need one or two of them.

• MDArray.swift - documentation - Contains the main MDArray type declaration. If you only need MDArray's storage handling, then you can get away with only including this file in your project.
• MDExtensions.swift - documentation - Adds computational functions to the MDArray type such as calculating determinants and determining symmetry/antisymmetry.
• MDMath.swift - documentation - Contains binary/unary operators and is the file responsible for utilizing the Accelerate framework to accomplish mathematical computations between MDArrays.

Please read the documentation for each of the files that you use in your project to get a general idea of how they are used.

Contributing

There is still work to be done! Please feel free to contribute to any of the following areas.

• Complex number support (MDMath should handle DSPSplitComplex and DSPDoubleSplitComplex vDSP functions)
• Row reductions
• Multidimensional array inverse, outter/inner products.
