r5.07.01 Calculating nonlinear modes with operator MODE_NON_LINE

Summary:

The operator MODE_NON_LINE makes it possible to calculate the nonlinear modes of an autonomous conservative linear system with localized shock nonlinearities. The numerical methods used for the calculation of non-linear modes are described here.
