  • package scalation

    The scalation package specifies system-wide constants for directory paths.

    The scalation package specifies system-wide constants for directory paths. Sub-packages may wish to define 'BASE-DIR = DATA_DIR + ⁄ + <package>' in their own 'package.scala' files. For maintainability, directory paths should only be specified in 'package.scala' files.

object MatrixD extends Error with Serializable

The MatrixD companion object provides operations for MatrixD that don't require 'this' (like static methods in Java). It provides factory methods for building matrices from files or vectors.
