In [4] a new representation for solutions of the Sturm-Liouville equation (pu')'+qu = {omega}{sup 2}u in terms of a nontrivial solution of (pu{sub 0}{sup '})'+qu{sub 0} 0 was obtained with the aid of the theory of pseudoanalytic functions and their relationship to solutions of the stationary two-dimensional Schroedinger equation. The representation has a simple and easily verifiable form and lends itself to numerical computation. We discuss its applications to numerical solution of corresponding boundary value and spectral problems. For example, using this representation a spectral Sturm-Liouville problem reduces to finding zeros of an analytic function whose Taylor coefficients are constructed explicitly.
