i want to find figure 2 for 'FRACTIONAL ZERO',i took the values as per the paper but both the graph is not crossing each other as shown in the figure,the code is given below

clc;

hold off;alpha=0.9;

Wcr=2.15845;a=2;

w1=logspace(-2,log10(Wcr),1000);w2=logspace(log10(Wcr),2,1000);

Mag1= (20*log10(abs(a)))*ones(1,numel(w1));Mag2=@(w2) 20*alpha*log10(w2);

semilogx(w1,Mag1);hold on;semilogx(w2,Mag2(w2));

grid on;xlabel('Frequency');ylabel('Magnitude dB')

clc;

clear

syms w alpha

alpha=0.9;a=2;w=logspace(-2,2,1000);

Mag1=@(w) (20*log10(abs(sqrt(((1j.*w).^alpha + a).^2))));

semilogx(w,Mag1(w));hold on;grid on;

xlabel('Frequency (rad/sec)');ylabel('Magnitude (dB)')
