# m_function_reihe

### synopsis: INT m_function_reihe(INT (*f)(); OP a);

### description:

you enter a function f, which computes an coefficent of the series, which is specified by an paramter of the function. The result is a object a of type REIHE. The syntax of the function f is described now in detail: INT f(OP a,b) a is a INTEGER object which gives the common degree of the coefficents, which should be computed. The result b must be of the type POLYNOM object. This POLYNOM object is homogenous of the entered degree.### example:

the following routine computes the series sum over all partitions, entered in exponent notation #include "def.h" #include "macro.h" INT co_part(a,b) OP a,b; { if (S_I_I(a) == 0L) m_iindex_iexponent_monom(0L,0L,b); else { OP c = callocobject(); OP d; INT i; makevectorofpart(a,c); init(POLYNOM,b); for (i=0;i
