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? And are there functions to compute the singular values/vectors of a matrix? How about the inverse of a square full-rank matrix? btw. what is new in the new boost library version 1.33? Vivid

Hi,

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.
Are there existing functions to compute LU, QR decompositions? Thanks a lot. Vivid --- Uwe Schmitt <schmitt@num.uni-sb.de> wrote:
