Exception for Octave 3.8, jcobi/3

\[\alpha \gt -1 \land \beta \gt -1\]

Math

\[\frac{\frac{\frac{\left(\left(\alpha + \beta\right) + \beta \cdot \alpha\right) + 1}{\left(\alpha + \beta\right) + 2 \cdot 1}}{\left(\alpha + \beta\right) + 2 \cdot 1}}{\left(\left(\alpha + \beta\right) + 2 \cdot 1\right) + 1}\]

C

double f(double alpha, double beta) {
        double r8408 = alpha;
        double r8409 = beta;
        double r8410 = r8408 + r8409;
        double r8411 = r8409 * r8408;
        double r8412 = r8410 + r8411;
        double r8413 = 1.0;
        double r8414 = r8412 + r8413;
        double r8415 = 2.0;
        double r8416 = r8415 * r8413;
        double r8417 = r8410 + r8416;
        double r8418 = r8414 / r8417;
        double r8419 = r8418 / r8417;
        double r8420 = r8417 + r8413;
