Try this:
x=[0:25:200];
y1= [0.4 0.29 0.21 0.19 0.13 0.11 0.09 0.05 0.006];
y2= [0.45 0.27 0.231 0.202 0.12 0.13 0.11 0.062 0.0062];
plot(x,y1,x,y2)
xticks(x)

Maybe you are using an older Matlab version, as it was introduced relatively recently, you can still do this though:
x=[0:25:200];
y1= [0.4 0.29 0.21 0.19 0.13 0.11 0.09 0.05 0.006];
y2= [0.45 0.27 0.231 0.202 0.12 0.13 0.11 0.062 0.0062];
plot(x,y1,x,y2)
set(gca,'XTick',x)
