The specific impulse response calculated by impulse is the dynamic multiplier, defined as the partial derivative of the output response with respect to an innovation shock at time zero for a univariate arima process, y t. The impulse response function for a univariate arima process is the dynamic response of the system to a single impulse, or innovation shock, of unit size.

Use the pulstran function to generate a train of custom pulses. If x is a vector, fft computes the dft of the vector. If x is a matrix, then envelope operates independently over each column.
