Matrix programming of electronic analog computers

Matrix programming of differential equations for electronic analog computers organizes the equations, thereby minimizing chances for errors; simplifies the scaling of coefficients and variables to suit the characteristics of the available machine; and in many instances permits the reduction of the number of “sign changers.” The matrix method furthermore helps safeguard against the appearance of extraneous terms in the solutions of certain systems of differential equations. These very practical attributes of the matrix method of programming save computing time and equipment.
