Exception for Numeric.Signal:interpolate from hsignal-0.2.7.1

• Falling back on racket egraph because egg-herbie package not installed

Math

\[x + \left(y - z\right) \cdot \frac{t - x}{a - z}\]

C

double f(double x, double y, double z, double t, double a) {
        double r9759 = x;
        double r9760 = y;
        double r9761 = z;
        double r9762 = r9760 - r9761;
        double r9763 = t;
        double r9764 = r9763 - r9759;
        double r9765 = a;
        double r9766 = r9765 - r9761;
        double r9767 = r9764 / r9766;
        double r9768 = r9762 * r9767;
        double r9769 = r9759 + r9768;
        return r9769;
}
