Chapter 6 Tutorial

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( ).
