  SPSMAT (Spectral/Pseudospectral matrix method) is an add-on for Octave, that
helps you solve nonfractional-/fractional ordinary/partial
differential/integral equations. In this version, as the first version, the
well-defined spectral or pseudospectral algorithms are considered to solve
differential and integral equations. The motivation is that there are few
software packages available that make such methods easy to use for
practitioners in the field of scientific computing. Additionally, one of the
most practical platforms in computation, MATLAB, is currently not supporting
beneficial and free numerical method for the solution of differential
equations--to the best author's knowledge. To remedy this situation, this paper
provides a description of its relevant uploaded open source software package
and is a broad guidance to describe how to work with this toolbox.
