We study systems of higher-order linear differential equations having a regular singularity at the origin. Using the properties of matrix polynomials, we develop efficient methods for computing their regular formal solutions. Our algorithm handles the system directly without transforming it into a system of first-order but higher size. We give its arithmetic complexity and discuss the results of an implementation in Maple.
