Extension of Mpdx matrix for 4th order partial differential equations with two independent variables

The use of Matrix of Partial Derivatives of the State Vector (Mpdx) method for numerical simulation of distributed parameter processes modeled by partial differential equations is considered to be known. In this paper is presented a new approach of computing the (Mpdx) matrix based on 4th order partial differential equations with two independent variables, time (t) and propagation space (s). Using a concrete example, the MpdxIV.2 matrix is computed and the results are presented both in tabular and graphical form.
