Re: [eigen] Uninitialized memory?

Hi,

Yes I am calling analyzePattern.

                SparseLU<SparseMatrix<Real, ColMajor>, COLAMDOrdering<int> > solver;

                solver.analyzePattern(matrixA); 

                solver.factorize(matrixA);

Did you call analyzePattern(matrixA) before that? Or could the structure of matrixA have changed?
You can use solver.compute(matrixA), if you are not sure about either of the above.
