Different results while using scilab 4.1.2 and 5.3

[Marcin Walczak]

Hi

I was using scilab 4.1.2 and lately I've decided to change it to
version 5.3. When I was testing the newer scilab 5.3 I noticed that
there are some differences between results from the older version. I
don't know what is the reason of such behaviour. I'm sending you a
picture with curves (look at the values on the left) and the code so
you could see it on your own. I would be glad if you could help me
with solving this problem
I'm looking foward for your reply

Martin
