2.3.0: Algebra & Random improvements

What's Changed

New Features

• Added Vector<Scalar> type (#110).
• Added diagonal/eye/identity & closure initializers to Matrix<Scalar> (#111, #134).
• Added shape property to Matrix<Scalar> (#152).
• Added variance function (#133).
• Added random/randomNormal functions for efficiently generating batches of random values (#154, #156).

Maintenance

• Migrated project to use Swift 5 (#97).
• Improved project documentation in README file (#103, #112, #115, …).
• Greatly improved project's unit test suite (#104, #108, #110, #118, #119, #120, #122, #127, #129).
• Added a benchmark suite (#123, #126).

Element-wise operators

The plus + operator is used by Swift for array concatenation. This caused some confusion with Surge's + element-wise addition. For this version all element-wise operators are preceded by a dot: .+.

This version also updates to Swift 4.0 and adds a few extra functions.

Swift 3.2

It took a while but it's finally here. This version support Swift 3.2 and Xcode 9.

Other changes include:

• Fix Matrix initialization bug
• Add Swift Package Manager support
• Fix Carthage support.
• Make rows and columns properties public
• Add sum of square values.
• Add some helper methods for matrix
• Add subscript support to return specific row or column
• Add support for scaling matrix by row or by column
• Make pow support applying to every element
• Add subtract method and operator

Final Release targeting Swift 1.x

This release is the last version to support Swift 1.0. Surge 2.x releases will support Swift 2.0.
