# TSARKIMEX2C
Second order ARK IMEX scheme with L-stable implicit part. This method has one explicit stage and two implicit stages. The implicit part is the same as in TSARKIMEX2D and TSARKIMEX2E, but the explicit part has a larger stability region on the negative real axis. This method was provided by Emil Constantinescu.
