This function was completely hacked together as I'm new to uBLAS (and rusty with linear algebra), but it got rid of most of my compile errors. Now only a few remain but I'm not sure what I'm doing wrong. I'm hoping that it will be obvious to someone here.
I tried to recreate your problem. Supposing that you defined somewhere in the enclosing scope newP, K and M you can easily compile the above sample by including #include <boost/numeric/ublas/matrix.hpp> // 1 #include <boost/numeric/ublas/traingular.hpp> // 2: not logical #include <boost/numeric/ublas/lu.hpp> // 3 I suppose you have line 1 (for having matrix) and 3 (since you're using the lu factorization) in your program but did not include triangular.hpp (why should you?). Actually this file should be included by lu.hpp but it is not. Hope this helps ! BTW, you best direct all your questions to the dedicated ublas-dev mailinglist to get more responses. Ublas-developers, can I add the include of triangular.hpp to lu.hpp ? toon
