Edvin Deadman and I have updated the catalogue of software for matrix functions that we produced in 2014 (and which was discussed in this post). The new version, which has undergone some minor reorganization, is available here. It covers what is available in languages (C++, Fortran, Java, Julia, Python), problem solving environments (GNU Octave, Maple, Mathematica, MATLAB, R, Scilab), and libraries (GNU Scientific Library, NAG Library, SLICOT).

Here are some highlights of changes in the last two years that are reflected in the new version.

- MATLAB functions expm and logm have been improved.
- Several new MATLAB third-party functions have been written, by various authors.
- The NAG Library Mark 25 has been released, which includes many new codes for matrix functions.
- Matrix function support in Julia has improved.

Other changes to the catalogue include these.

- SLICOT has been added.
- Two more R packages are included.

Suggestions for inclusion in a future revision are welcome.
