Alternatives to the Particle-Size Toolbox
Not everybody has access to Matlab, nor is it necessarily the best way to do everything. Below is a list of alternatives to running the Particle-Size Toolbox in Matlab, which I hope will help to broaden the treatment of particle-size distributions as compositional data.
If you are interested in porting the PST to another programming language please get in contact.

. Although Octave is very similar to Matlab, it may require some in-script changes to run correctly, particularly if additional toolboxes are required. NB: If you're not very familiar with your computer system's command line interface or you don't have C-compiler installed I recommend downloading a
