Description
when I solve a general eigenvalue problem with Arpack package, I found that it doesn't work when its version is 0.5.4. When i switch the version to 0.5.3, it is done well.
Error info in 0.5.4:
n=201
┌ Error: XYAUPD_Exception: Maximum number of iterations taken. All possible eigenvalues of OP has been found.
│ IPARAM(5) returns the number of wanted converged Ritz values.
│ info = 1
