        !             7: .SH DESCRIPTION
        !             8: .I Matlab
        !             9: manipulates complex matrices interactively.
        !            10: Special cases include
        !            11: real matrices and scalars.
        !            12: Operations include pseudoinversion (which
        !            13: is inversion for square nonsingular matrices), eigendecomposition,
        !            14: various other factorizations, solution of linear equations, matrix
        !            15: products (including inner and outer products), Kronecker products,
        !            16: log, exponential and trigonometric functions of matrices, and rank and
        !            17: condition estimation.
        !            18: .PP
        !            19: Variables are alphanumeric strings of at most
        !            20: 4 characters.
        !            21: Case is ignored.
        !            22: Expressions and assignment statements are written
        !            23: as in Fortran.
        !            24: Multiple statements can be put on one line,
        !            25: separated by either comma or semicolon; the result of a statement
        !            26: is written on the standard output unless a semicolon follows the statement.
        !            27: Extensions to Fortran notation include:
        !            28: .PP
        !            29: .I Matrix construction
        !            30: from elements.
        !            31: Elements in a row are separated by commas; columns are
        !            32: separated by semicolons; matrices are surrounded by
        !            33: .L  < >
        !            34: brackets.

        !            40: .I Consecutive integers
        !            41: are denoted by colons in the style 1:4 or 1:2:8 (meaning 1,3,5,7).
        !            42: .L A(2:5)
        !            43: is a subarray;

        !            50: its dimensions are dictated by context.
        !            51: .PP
        !            52: .I Reverse division
        !            53: is denoted by \e .
        !            54: For example,
        !            55: .L x = A \e b
        !            56: is roughly the same as
