Inversion of a complex matrix

by a c a rd containing (x, n), where x is the symbol in powers of which the division is to be perforated, and where n specifies t he number of division steps to be taken. The input a r r angemen t of l"(:c) and D(x) is arbitrary, sinee the p rogram determines the "standard form" during the division process . Output: The program prints the card containing (x, n). After division has been performed, tho program constructs and prints a string of the form (F(x))/(D(:c)) = Q(x); if' R(:c) = 0 the comment xo a~x~Mxm, m apl)ears, otherwise, R(x) is also printed out. Figure 2 is a prb~tout preduced by this program.
