Eigenvalues of field-dependent mass automatically #13

Hi Max,

In testModel1.py file, you used the manual definition of eigenvalues of the field-dependent mass matrix in 'boson_massSq' function.

Is it possible to use the 'eigvalsh' function from 'scipy'? I have tried this but I got an error, it seems that is due to the shape of 'X' in some steps which results in a non-square matrix.

Cheers, Sam

Solved.

Dear Colleague， I have been struggling to solve the problem, but fail. Could you share me with your solution? Many thanks

Hi All,

I have encountered exactly a similar problem and stuck to that part. Get the following error message after using "np.linalg.eig" to diagonalize a 3x3 field-dependent matrix under 'bosob_massSq'. "LinAlgError: Last 2 dimensions of the array must be square"

Could you kindly let me know how you solve that problem? Many thanks in advance.

Regards, Subhojit
