s=poly(0,'s'); tf=(s+1)/((s-1)*(s+2)*(s+3)); H=tf2ss(tf);evans(H,5)
this works in scilab and the cloud
s=poly(0,'s'); tf=(s+1)/((s-1)*(s+2)*(s+3)); H=tf2ss(tf);evans(H,5); sgrid()
this also works, but the sgrid() doesn't show up in scilab. Strange thing, it does work in the cloud.
It does work for me on local scilab.
The cloud must have been down for a while, since I see that now the code is working in the cloud (days later). I still do not get the same results when I use the code in the Scilab tool. I have seen no reason for this. The sgrid() code still does not show, only the root locus plot. Maybe there is a bug Scilab when using Windows 8.1, but can find no related bug reports. This is baffling!.
