Hello everyone
I just want to ask if anyone could help me or at least tell me if it is possible to solve the couple equations using matlab
I saw ode45 but that is for one equation only
Thank uou

ODE45 works for systems of equations. You just write the function that calculates the derivatives to take a vector of y values and return a vector of the derivatives.

See the examples in http://www.mathworks.co.uk/help/matlab/ref/ode45.html
