28             Scilab 関数 <literal>[b]=Noise(t)</literal>を生成します.
29             ただし, <literal>Noise(t)</literal>は区分定数関数です
30             (<literal>[k*pas,(k+1)*pas]</literal>の区間は定数).
31             各一定区間の値は,
32             互いに独立で同一の分布に従う標準偏差 sig のガウス分布
33             によるランダムな値です.
34             関数は,<literal>t&lt;=0</literal>および
35             <literal>t&gt;=Tmax</literal>では一定です.
