Hi,

I'm deep into math and wonder if anybody has implemented the Newton Raphson
algorithm for minimization. I want to do multidimensional scaling; I have a
distance matrix between points and want to represent the points in a
lowdimensional space with the minimum of stress possible on the distance
matrix.

Thanks
