No, not at all, I'm glad that I do get the decomposition for non-square
matrices. My problem is not with elu$U but with as.matrix(elu$U), which is
not an upper diagonal matrix. Can I do something to fix this ?
Regards, Ulrike

Dear R-helpers,
I have a question regarding LU-decomposition with function lu in package
Matrix. The following simple example confuses me: Why is as.matrix(elu$U)
not an upper triangular matrix?
u3 <-
matrix(c(1,1,1,1,1,1,-1,1,0,0,0,0,0,-1,1,0,0,0,-1,0,1,0,0,0,0,0,-1,1,0,0),5,6,byrow=T)
elu <- e
