Finding initial value

Hello,
if I use numerical solver for nonlinear problems (like ode or fsolve) I need a good initial value (initial value problem). The problem is, if I use such solver I get following message (here the solver is: ode15s):
Need a better guess x0 for consistent initial conditions.
or sometimes I get the error:
This DAE appears to be of index greater than 1.
My question is, is there a method in MATLAB to get a good initial guess? I know that with Homotopy it is possible to get a good initial guess....maybe MATLAB has such thing.....
Thank you for your help

Thank you,
