Clifford Multivector Toolbox release 1.2

We are pleased to announce the release of version 1.2 of the
Clifford Multivector Toolbox:

Clifford Multivector Toolbox for Matlab

Release Notes

Version 1.2 10 May 2017

The subsasgn function has been corrected to deal with cases like assignment
of empty to a row or column of a multivector array, and cases where parts
some components of the assignment source or destination were empty.
Thanks to Radek Tichy for pointing out cases where this function failed.

Test code has been added for Matlab functions known to work with multivector
inputs. This code is mostly copied from the Quaternion Toolbox for Matlab.
While debugging it, a change was made to the .* and + functions to permit
singleton expansion by removing a check on the sizes of the parameters. This
step follows similar changes made in QTFM to support the new functionality
of Matlab since release R2016b. Further work may be needed to permit
implicit singleton expansion in other functions. The list of Matlab functions
which work with multivectors has been corrected.

The mean function has been added to the toolbox (in order to support the
tests above on the std and var functions).
