Is there anyone can help me on how to get an ODE45/ODE15 program to solve the above equation?
I want to get the value of y1 and y2.
Thanks,

Since the system appears to describe a differential-algebraic equation, see the documentation section on Solve Differential Algebraic Equations (DAEs) that describes how to set it up symbolically in order to use ode15i to integrate it numerically.
