Sparse N-Dimensional Arrays

This is a (still incomplete) implementation of Sparse N-Dimensional Arrays based off of GSL's SPMatrix.

Roadmap:

Operations

  • allocate
  • free
  • get
  • get variadic
  • set
  • set variadic
  • IncrementAt
  • Fill value

Arithmetic

  • Addition
  • Subtraction
  • Simple Multiplication
  • map 1/x
  • Multiplication with nonzero fill values
  • reduce one dimension by a given funcion

Memory Operations

  • copy
  • CCS compress

Fancy Operations

  • Extraction of dimensions
  • Reshape
  • Flatten
  • Partition
  • Subarray extract
  • Views

(PRs welcome!)
