The Mathworks has finally allowed the Matlab Student Version to include all releases–specifically the fall “b” releases as of Matlab R2015b. Formerly, only the spring “a” releases were available in the Matlab Student Version.
The toolboxes are currently $10 to add at the time of purchasing Matlab Student Version, or $29 later. For those involved with Geospace research, I suggest the Aerospace and Mapping Toolbox.
For most, I suggest the Parallel Computing Toolbox.
If you are still using Matlab R2014a or older, you are really missing out on cool features including the new plotting system and Python integration.
