semilogy plotlib issue

[G V V Sharma]

Hi,
	I'm unable to run the following code on my Ubuntu 11.04, Scilab 5.3.  Plotlib has been installed.  I did perform an upgrade from 10.10 after installing scilab.

w=logspace(-2,2,200);
s=%i*w;
g=1../(s.^2+0.01*s+1);
_semilogy(w,abs(g));



regards,
Vishwanath.
