Exception for Octave 3.8, jcobi/2

\[\alpha \gt -1 \land \beta \gt -1 \land i \gt 0.0\]

Math

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

C

double f(double alpha, double beta, double i) {
        double r8194 = alpha;
        double r8195 = beta;
        double r8196 = r8194 + r8195;
        double r8197 = r8195 - r8194;
        double r8198 = r8196 * r8197;
        double r8199 = 2.0;
        double r8200 = i;
        double r8201 = r8199 * r8200;
        double r8202 = r8196 + r8201;
        double r8203 = r8198 / r8202;
        double r8204 = r8202 + r8199;
        double r8205 = r8203 / r8204;
        double r8206 = 1.0;
        double r8207 = r8205 + r8206;
        double r8208 = r8207 / r8199;
        return r8208;
