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 r8178 = alpha;
        double r8179 = beta;
        double r8180 = r8178 + r8179;
        double r8181 = r8179 * r8178;
        double r8182 = r8180 + r8181;
        double r8183 = 1.0;
        double r8184 = r8182 + r8183;
        double r8185 = 2.0;
        double r8186 = r8185 * r8183;
        double r8187 = r8180 + r8186;
        double r8188 = r8184 / r8187;
        double r8189 = r8188 / r8187;
        double r8190 = r8187 + r8183;
