28 <literal>noisegen()</literal> is obsolete. It will be removed from Scilab 6.1.x.
29 Please use grand() instead. Examples (clearer, shorter, and more powerful) follow:
32 100 10-point wide steps with random amplitudes of normal distribution
33 of mean 1 and standard deviation 0.7:
35 <programlisting role="example"><![CDATA[
36 u = grand(1,100,"nor",1,0.7) .*. ones(1,10);
41 40 15-point wide steps with random amplitudes of uniform distribution in [1 3],
42 with initial level 0.5 and final level hold:
44 <programlisting role="example"><![CDATA[
46 u = grand(1,40, "unf", 1, 3) .*. ones(1,width);
47 u = [ones(1,8*width)*0.5, u, ones(1,5*width)*u($)];
52 Scilab 関数 <literal>[b]=Noise(t)</literal>を生成します.
53 ただし, <literal>Noise(t)</literal>は区分定数関数です
54 (<literal>[k*pas,(k+1)*pas]</literal>の区間は定数).
56 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
58 関数は,<literal>t<=0</literal>および
59 <literal>t>=Tmax</literal>では一定です.
