Question 1

How do I install Matft in my Swift project?

Accepted Answer

The recommended way is via Swift Package Manager in Xcode; Carthage and CocoaPods support is outdated. Add Matft as a dependency in your Package.swift or through Xcode's UI.

Question 2

Is Matft as fast as NumPy for all operations?

Accepted Answer

No, Matft excels in arithmetic and math functions using Accelerate, but boolean operations are significantly slower. Benchmarks in the README show mixed performance, with boolean tests taking up to 19.7ms vs NumPy's 1.78ms.

Question 3

How to convert an image to an array in Matft?

Accepted Answer

Use `Matft.image.cgimage2mfarray` to convert a CGImage to MfArray for pixel manipulation, then convert back with `mfarray2cgimage`. Example code in the README demonstrates reversing and swapping channels.

Question 4

Does Matft work with complex numbers for scientific computing?

Accepted Answer

Yes, Matft supports complex arrays with operations like addition, conjugation, and angle calculation. However, it's in beta, so some features like boolean indexing setter are missing, and bugs may occur.

Question 5

Matft or Python NumPy for iOS development?

Accepted Answer

Choose Matft if you need native Swift integration without Python interop for array operations. However, Matft lacks Python's extensive libraries and has slower boolean indexing, so for broader data science, NumPy with Python might be better.

Question 6

How to handle indexing in Matft for 1D arrays to get scalars?

Accepted Answer

For 1D arrays, use the `.item` method instead of direct subscripting, as subscripting returns an MfArray. For example, `a.item(index: 0, type: Int.self)` gets the scalar value, avoiding the MfArray wrapper.

Question 7

Can Matft be used for machine learning in Swift?

Accepted Answer

Matft provides linear algebra and array operations, but it doesn't include ML algorithms. You'd need to integrate it with other Swift ML libraries like Swift for TensorFlow or create custom implementations, limiting out-of-the-box functionality.
