NAME    inverse - inverse of valueSYNOPSIS    inverse(x)TYPES    If x is an object of type xx, the function xx_inv has to have    been defined; any conditions on x and the nature of the returned    value will depend on the definition of xx_inv.    For non-object x:    x		nonzero number (real or complex) or nonsingular matrix    return	number or matrixDESCRIPTION    For real or complex x, inverse(x) returns the value of 1/x.    If x is a nonsingular n x n matrix and its elements are numbers or    objects for which the required arithmetic operations are defined,    inverse(x) returns the matrix m for which m * x = x * m = the unit    n x n matrix.  The inverse m will have the same index limits as x.EXAMPLE    ; print inverse(5/4), inverse(-2/7), inverse(3 + 4i)    .8 -3.5 .12-.16i    ; mat A[2,2] = {2,3,5,7}    ; print inverse(A)    mat [2,2] (4 elements, 4 nonzero):	[0,0] = -7	[0,1] = 3	[1,0] = 5	[1,1] = -2LIMITS    noneLINK LIBRARY    void invertvalue(VALUE *x, VALUE *vres)    NUMBER *qinv(NUMBER *x)    COMPLEX *c_inv(COMPLEX *x)    MATRIX *matinv(MATRIX *x)SEE ALSO## Copyright (C) 1999  Landon Curt Noll#### Calc is open software; you can redistribute it and/or modify it under## the terms of the version 2.1 of the GNU Lesser General Public License## as published by the Free Software Foundation.#### Calc is distributed in the hope that it will be useful, but WITHOUT## ANY WARRANTY; without even the implied warranty of MERCHANTABILITY## or FITNESS FOR A PARTICULAR PURPOSE.
