Abstract. A collocation procedure is developed for the initial value problem u (t) = f (t, u(t)), u(0) = 0, using the globally defined sinc basis functions. It is shown that this sinc procedure converges to the solution at an exponential rate, i.e., O(M 2 exp(−κ √ M )) where κ > 0 and 2M basis functions are used in the expansion. Problems on the domains R = (−∞, ∞) and R + = (0, ∞) are used to illustrate the implementation and accuracy of the procedure.
