[0.5] - 2021-09-13

Added (major)

  • Support for signed and unsigned integral and floating point weights
  • Add the Matrix class, which is non-symmetric by default, and added
    SymMatrix for the specialized symmetric case (represented only by
    a CSR).
  • Added a DiGraph (directed graph) class, similar to a Matrix but with
    graph-specific naming and in-edge and out-edge iterators.
  • Added support for writing out COOs to ASCII files
  • Added support for upper-triangle handling in COO template parameters
  • Added support for removing multiple edges by a CSR generation method,
    new_csr_without_dups

Added (minor)

  • Support for easily computing the vertex degree (non-zeros in a row)
  • Support for changing label and ordinal types between CSR and COOs
  • Automatic detection and appropriate handling of 1-based .graph files
  • Test file for removing self loops
  • Support for symmetrizing inputs, along with a timer and test
  • Support for returning the number of rows and columns for rectangular CSRs
  • Support for transposing COOs
  • Support for copying COOs
  • Support for (weighted) graphs
  • Support for changing the number of rows, cols, and labels in COOs
  • Support for reading and writing binary directed graphs
  • Added a release generation script to create a single header file
  • Added support for sorting CSRs
  • Support for creating a fixed-sized uninitialized COO
  • Added an example for finding an edge in a graph
  • Added const to size returning methods in COO and CSR

Breaking changes (minor)

  • Removed the Matrix alias due to adding full (non-symmetric) Matrix
    support
  • Changed symmetrizing to not introduce multiedge diagonals
  • Removed the option for the COO to remove multi edges

Fixed

  • Fixed support for converting from shared_ptr COOs to CSRs
  • Fixed passing template arguments from CSR to COOs
  • Fixed setting n for matrix market files instead of just nrows/ncols
  • Fixed symmetrizing with weights
  • Fixed a bug where nrows and ncols were not saved in CSR binary files
  • Fixed CMake to ensure anything that uses PIGO is linked with OpenMP
  • Fixed the detection of Linux-specific file opening options to not detect GCC
