I have equations as(adsbygoogle = window.adsbygoogle || []).push({});

C1*y1' = F*C2*y2 - C3*y1

y2' = C4 -B* C5*y3 - C6*y1

y2-C7=x(t)*y3

X(t) is a known function

where F = 0 when y3<y1

1 when y3>y1

B=0 when C7<y3

1 when C7>y3

C's are constants

so what I am thinking is at time t1 i will get the values for F and B depending on previous values and X value will be known and I need the solution for the unknowns at time t1. I tried solving this by newton raphshon method but the solution is not converging. Are there any MATLAB commands for this like ODE 23 OR any new solution is welcomed

Thanks a lot
