I am trying to solve a system of differential equations numerically, preferably using the ode45 command. The equations are as follows-

dx/dt = f(x,y)*g(x)

dy/dx = h(x)

Both 'x' and 'y' are dependent variables and 't' is the independent variable

What did you try so far and state your equation explicitly.

Hi Nishant,

If you convert the second equation to

dy/dt = h(x)*dx/dt

then you have a system where dy/dt and dx/dt can be specified in terms of x and y, so ode45 will apply.
