mult

synopsis: INT mult(OP a,b,c)

description:

it multiplies the two objects a and b and the result will be in c. First there is a check whether a,b,c not NULL then whether a and b are no empty objects. Then it frees the object c. Now it multiplies. It is not necessary, that a,b,c are different. See also mult_apply(); Multiplies two objects, and the result is a new object. Look at the following list of possible datatypes. BRUCH,CYCLOTOMIC,GRAL,FINITEFIELD, HOM_SYM, INTEGER,KRANZTYPUS,KOSTKA,LONGINT,MATRIX,MONOPOLY PERMUTATION,POLYNOM,SCHUR,SCHUBERT,REIHE SYMCHAR,SQ_RADICAL,VECTOR.

return:

OK or ERROR

bugs:

many combinations are missing

example:

 main() {
 OP a = callocobject();
 OP b = callocobject();
 scan(POLYNOM,a);
 scan(BRUCH,b);
 mult(a,b,b); println(b);
 freeall(a);
 freeall(b);
 }
 This example multiplies a BRUCHobject and a POLYNOMobject, which
 gives a POLYNOMobject with BRUCHobjects as coefficients.
