Dear all,As a reply to my own post, there is definitely a problem in the linear algebra operations in gmm++ from accuracy point of view. I tested my problem with MTL4 and the results seem to be far more close to what they should be. I am not sure what the problem is in gmm++ but this deserves some attention. I can provide a test case in MATLAB and gmm++ where I compare these tridiagonal coefficients of the lanczos proces. To test the MATLAB code, one should have the MUMPS MATLAB interface installed. Best regards, Umut
