Dear professor,  
I am doing a two sector model with Gertler bank. I found a very strange thing. The model could run well with the initially set parameter. However, when I change any parameter value, the model reports error. For example, the initial value is 0.381, the model could run well. When I change it slightly to 0.38, the model reports error.Other parameters are similar. So, I could not change any parameter value,I don’t know the reason. Could you help me to solve this problem, Thanks.

The `param_GH2b.m` is missing.

Dear professor, I have attached the parameter file, please have a look.
