I wonder if I have two coupled differential equations( ex. first orders) with two unknows coeffcients, which ode solver shouls I use for
I have tried using ode45, but I dont have initial values for this, so I wonder if there is an ode solver that could guess or implement that function?
Thanks, Hope for an answer!

In some situations, this can be coded as a Boundary Value Problem https://www.mathworks.com/help/matlab/boundary-value-problems.html?s_tid=CRUX_lftnav in which you are trying to find coefficient values that match some known behaviour.
But in the more general case, you cannot use numeric methods because you are modeling a class of problems, and you have to hope that the Symbolic Toolbox dsolve() can figure out a useful solution for you.
