MATLAB: How can I transform this code into a for loop

for loop

subplot(3,3,1)
[S,f]=myFFT (x(0.1*fs:0.35*fs),fs); 
plot(f,abs(S))
subplot(3,3,2)
[S,f]=myFFT (x(0.4*fs:0.65*fs),fs); 
plot(f,abs(S))
subplot(3,3,3)
[S,f]=myFFT (x(0.7*fs:0.95*fs),fs); 
plot(f,abs(S))
subplot(3,3,4)
[S,f]=myFFT (x(1.3*fs:1.55*fs),fs); 
plot(f,abs(S))
subplot(3,3,5)
[S,f]=myFFT (x(1.6*fs:1.85*fs),fs); 
plot(f,abs(S))
subplot(3,3,6)
[S,f]=myFFT (x(1.9*fs:2.15*fs),fs); 
plot(f,abs(S))
subplot(3,3,7)
[S,f]=myFFT (x(2.2*fs:2.45*fs),fs); 
plot(f,abs(S))
subplot(3,3,8)
[S,f]=myFFT (x(2.5*fs:2.75*fs),fs); 
plot(f,abs(S))
subplot(3,3,9)
[S,f]=myFFT (x(2.8*fs:3.05*fs),fs); 
plot(f,abs(S))

Best Answer

a=[0.1, 0.3, 0.6, 1.3, 1.6, 1.9, 2.2, 2.5, 2.8];
b=a+0.25;
for i=1:9
    subplot(3,3,i);
        
    [S,f]=myFFT(  x(  a(i)*fs : b(i)*fs ) , fs); 
    
    plot(f,abs(S))
end
