To get the numerical response values:
Compute the FIR model by using
as described in Estimate Impulse-Response Models at the Command Line.
Apply the following syntax on the resulting model:
% To compute impulse-response data [y,t,~,ysd] = impulse(model) % To compute step-response data [y,t,~,ysd] = step(model)
y is the response data,
the time vector, and
ysd is the standard deviations
of the response.
