Compute Response Values

You can use impulse and step commands with output arguments to get the numerical impulse- and step-response vectors as a function of time, respectively.

To get the numerical response values:

1. Compute the FIR model by using impulseest, as described in Estimate Impulse-Response Models at the Command Line.

2. Compute the response of the resulting model.

   • Compute impulse-response data.

     [y,t,~,ysd] = impulse(model)

   • Compute step-response data.

     [y,t,~,ysd] = step(model)

   Here, y is the response data, t is the time vector, and ysd is the standard deviations of the response.
