has anyone had any success with integral equations? I have a system of ODE's, one of which involves the function r"t" which is an integral equation. I tried to define it like this: r"t_" := Integrate"x' "t" Exp"-(t-z)",(z,-Infinity,t)" etc. but later on when this was called from NDSolve, it didn't work. There is no reference to integr al equations in the Mathematica manual. Thanks in advance for any assistance| Jennifer Voitle <FAC3258%UOFT01.BITNET at pucc.Princeton.EDU>
