Subject: Fix Matrix template copy constructor
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=03f70f6ba9622bb2840a14fc50ac72201cc533b5;p=libs%2Fmath.git

Fix Matrix template copy constructor

A different version of the template is a different class, so the data
member can't be accessed directly.
