Solve Differential Algebraic Equations (DAEs) - MATLAB & Simulink

http://www.scholarpedia.org/article/Differential-algebraic_equations WebOne way to solve a high-index DAE system is the reduction of the index. Once the index of the DAE system is reduced to at most 1, a numerically stable solver with an index of 1 will be able to solve stably. For the above reasons, the index reduction is applied to the high-index DAE system. MATLAB and Mathematica can solve the DAE systems. These ... kurgo go tech adventure harness
