Example 1 with OpGroup

use of suite.math.sym.Express.OpGroup in project suite by stupidsing.

the class DivisiblePolynomial method format.

public Node format(Poly<N> poly) {
    Express ex = new Express();
    OpGroup add = ex.add;
    OpGroup mul = ex.mul;
    Int_Obj<Node> powerFun = p -> {
        Node power = mul.identity();
        for (int i = 0; i < p; i++) power = mul.apply(x, power);
        return power;
    };
    Node sum = format_.apply(n0);
    for (IntObjPair<N> pair : poly.streamlet().sortByKey(Integer::compare)) {
        int p = pair.t0;
        Node power = p < 0 ? mul.inverse(powerFun.apply(-p)) : powerFun.apply(p);
        sum = add.apply(mul.apply(format_.apply(pair.t1), power), sum);
    }
    return sum;
