I need to solve a ordinary second order differential equation, of the type y''[x] + P[x] y'[x] + Q[x] == 0, where the coefficients P[x] and Q[x] are an interpolating function (or a table of numerical data). I have tried with NDSolve, but it seems to admit only an interpolating function for Q[x], but not for P[x]. Does any one know what could I do? Regards, Daniel Arteaga
