Fix the loss of significance problem of single precision Wen-Yin Integration. #16

Open emfomy opened 7 years ago

emfomy commented 7 years ago

The single precision Wen-Yin Integration failed the unit tests. The norm of matrix M becomes negative after some iteration.

In the unit test, WY stopped in 13 iterations, while the correct iteration number is 21. I’ve check the value of mu (the norm of matrix M). The value becomes negative in the 13th iteration.
