Are there existing functions to compute LU, QR
decompositions?
Thanks a lot.

Hi,
I browsed the document of ublas for a long time and did not find a convenient way to compute the determinant of a matrix. Isn't it a basic function of matrix or did I miss something?
In general you can use LU-decomposition or QR, as det(A) = det(LU) = det(L)*det(U) or det(A) = det(QR) = det(R) The determinant of L, U, R is the product of the elements on the diagonal.
Greetings, Uwe.
