  伝達関数   
     $T(s)=\frac{1}{\frac{1}{sT_{C1R1}}+1} = \frac{sT_{C1R1}}{1+sT_{C1R1}}$    
 $( T_{C1R1}は時定数。 s はラプラス変数。 jω はsとする ) $
     TeX記述   
     $T(s)=\frac{1}{\frac{1}{sT_{C1R1}}+1} = \frac{sT_{C1R1}}{1+sT_{C1R1}}$

 プログラムです。

C1=0.001;
R1=1000;
numerator = [1*C1*R1,0];
denominator = [C1*R1,1];
sys = tf(numerator,denominator)
h = bodeplot(sys);
p = getoptions(h);
p.FreqUnits = 'Hz';
setoptions(h,p)
grid on

stepplot(sys);
h = nyquistplot(sys);
