PCA is what statisticians call eigen-vectors/values isn't it? I seem to recall Chris Brown wrote a package for the striper-ranger work, (surfaces for the fitting of) but unless Pat has kept a copy I doubt if the code is extant. I -do- have a generic interface to Numerical Recipies in C. Now I seem to recall that the matrix you get for stats. is symmetric, which is the easy case dealt with in that tome... Robin. |
