% We can couple the design of gain on the root locus with a % step-response simulation for the gain selected. We introduce the command % rlocus(G,K), which allows us to specify the range of gain, K, for plotting the root % locus. This command will help us smooth the usual root locus plot by equivalently % specifying more points via the argument, K. Notice that the first root locus % plotted without the argument K is not smooth. We...
