VALUE FUNCTIONOVERTAKING CRITERIONUPPER SEMICONTINUITYDYNAMIC SYSTEMSDefine the matrix A n as the sum of D n = ( d ij) and C n, where d ij = 1 when i| j and zero when i ∤ j, and where C n = (0, 1, 1, …, 1) T(1, 0, 0, …, 0). We use the Geršgorin disc ...
***WARNING: THE SYSTEM MATRIX HAS 1 NEGATIVE EIGENVALUES. In an eigenvalue extraction step the number of negative eigenvalues is equal to the number of eigenvalues below the current shift point. This may be used to check that eigenvalues have not been missed. Note: the lanczos eigensolver ...
The only difference was the one small eigenvalue which was negative in Fortran and positive in Octave. p.s. Octave also uses DSYEV Thanks!! Hello, It is interesting probelm. Could you pleaseprovide small test case(include the input matrix)to show the problem? Than...
