Generate Figure 6-8:
tvec=0:(140/99):140;
compare(syscl,sysclr,tvec,{type=7})
f8=plot({keep,legend=["original","reduced"]})
Figure 6-8. Step Response with ophank
The open-loop gain, closed-loop gain and step response are all inferior to
those obtained with
redschur( ) . This emphasizes the point that one
cannot automatically assume that, because the error bound formula for
ophank( ) is more attractive than that for redschur( ) , the error itself
will be better for ophank( ) .
