The code is tested on the gfortran compiler, with the "openblas" and "lapack" for accelerating the math calculation.

Following is an example of the control simulation experiment with Lorenz-63 model.

I hope the code provided here could be of some help to the control research with ensemble members. I always welcome any discussions and questions, please contact me through: [email protected].
