> As discussed in thread http://markmail.org/message/a4d454alexugur2m on the commons developers mailing list, it would be interesting to use an API similar to the one defined by the now defunct JAMA project (http://math.nist.gov/javanumerics/jama/).
> In order to follow current practice in commons-math, this implies creating interfaces corresponding to the JAMA classes, and to provide default implementations for them.
> The current LU decomposition based solve methods in RealMatrixImpl should be removed and replaced by the various sovle implementations provided by all the decomposition algorithms (LU, QR ...).
