Hello,
I want to simulate a state-space model (A,B,C,D) of the kind generated by the ss command in the Control Toolbox, but with a non-uniformly spaced time vector. The lsim command does not work, since it requires evenly spaced time samples.
Would you be able to suggest a way of generating state- and output values for this case?
Thank you in advance!

Hi @Paolo Rapisarda
I think you can possibly use the 1-D data interpolation technique, interp1() function at certain intervals of the query time points. For example
xq = interp1(t, x, tq, 'cubic')
For more info, please check other methods.
