f(x) = integral of 1 to 0 ( G(x,x') g(x') dx' )

G(x,x') = (sinh(x) . sinh(1-x')/ sinh(1)) if (x<x')

G(x,x') = (sinh(1-x) . sinh(x')/ sinh(1)) if (x'<x)

solve d2f(x)/dx2

and satisfy d2f(x)/dx2 + f(x) = g(x) with f(0) = f(1) = 0;

If I were you, I'd solve the differential equation directly using MATLAB's "bvp4c" and don't use the way over Green's function.

Best wishes

Torsten.
