Is this a mathematical result(the output of the eigenvector with both real and imaginary part)?     \r\n  I checked the Developer Information and went through the code roughly but didn't get the answer.\r\n\r\n2.The second quesion is about the resolution. Becoz I got a problem that if I improve the resolution to a very high level,e.g. set the resolution at 256 for a 2D case, the plot of the efield with 'h5topng' is distorted and strange, very different from those at resolution of 32 or 64.\r\n  So I wonder if there would be something wrong if the resolution is too high from the theory? \r\n\r\n I do hope these questions are non-trivial, but make me know if they are stupid:)\r\n Thank you.\r\n\r\nCheers,\r\nHanrong\r\n"}}
