See Section ?? in the MOST User’s Manual for any requirements speciﬁc to MOST.
For the hardware requirements, please refer to the system requirements for the version of Matlab11 or Octave that you are using. If the Matlab Optimization Toolbox is installed as well, Matpower enables an option to use it to solve optimal power ﬂow problems.
In this manual, references to Matlab usually apply to Octave as well. At the time of writing, none of the optional MEX-based Matpower packages have been built for Octave, but Octave does typically include GLPK.
