deriv :
A derivative operator for xreal-typed signals.

The deriv primitive computes the derivative of an xreal-typed signal in. For instance, if the input signal x(t) is cos(wt+phi), then the primitive will return an output dx(t)/dt equal to w*sin(wt+phi).

The parameter scale specifies an additional input scale factor, i.e.,

out = scale * d(in)/dt
