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 r9412 = x;
        double r9413 = y;
        double r9414 = z;
        double r9415 = r9413 - r9414;
        double r9416 = t;
        double r9417 = r9416 - r9412;
        double r9418 = a;
        double r9419 = r9418 - r9414;
        double r9420 = r9417 / r9419;
        double r9421 = r9415 * r9420;
        double r9422 = r9412 + r9421;
        return r9422;
