Re: [eigen] Convert 1x1 matrix to internal type?

[Thomas Capricelli <orzel@xxxxxxxxxxxxxxx>]

This, is really a dot product... a.dot(b)*c;

Actually, i think most of the time, when someone wants to cast a 1x1 matrix to a scalar, he missed a dot product somewhere.

And i'm against such an automatic casting as well.

Thomas
