I cant get my matlab programme to work,. HELP

  1. Apr 22, 2004 #1
    Hi! I have :eek: hand in an assigment in like four hours and part of it involves solving a IVP. We have to use the built in function ODE45. the system of equations are as follows.

    x'(t)=-axy
    y'(t)=axy-by
    z'(t)=by

    Use step length 1 and solve the ivp numerically for the following values of a,b
    a=0.00001, b=0.25
    a=0.0002, b=0.10

    I know its easy but i cant get it to work. Please help me. :redface:
