this is equivalent to solving the system :
[ X Y Z ] * ( a b c ) T
for abc.
if X,Y,Z have length higher than 3 you need to do leas squares
(apply the regression formula)

Subject: [ublas] Solving simple vector equation *newbie* 

I'm 100% new to ublas.  Can you help me get started?

I need to solve for a, b, c in the vector equation:

R = a*X + b*Y + c*Z

where R, X, Y, Z are known column vectors.

How do I do this in ublas?  Will you create or point me to a simple
example of how to do this?  Details will really help me here as I
haven't used ublas before, but I need it for several projects going
forward.

Thanks!
