[boost] [uBLAS] Strange behaviour of LAPACK binding for SVD drivers

Hello, I'm using LAPACK + bindings to do a Singular Value Decomposition of uBLAS matrices. For inverting a matrix, I need the U and the Vt matrix calculated explicitly. But whatever I give as Jobu and Jobvt, only the Vt matrix will be calculated correctly; the U matrix has only correct diagonal elements. I've tried the Jobu = 'A' setting for gesvd and the Jobz = 'A' setting for gesdd with exactly the same results as JobX = 'O'. I'm using the ublas bindings from CVS (checkout: last Friday, 09.09.2005). Can anybody give me a hint, what might go wrong here. Best regards, Peter
