Dear friends,

I would like to solve the following regression problem:

y=c1 x1 + c2 x2 + .... + cn xn

where the y, xi are all matrices and the ci are constants that need to be
determined. The y, xi are distance matrices (symmetric). ci should be forced
to positive or null (i.e. non negative).

Any suggestion?

I will be more than happy to share the results of my quest with the list or
developers.

Regards
