在 MATLAB Online 中打开

I don't about the last attached image...but with your phase amp.png and attached xl file. Run the below code.

clc; clear all
file = 'example_alumi.xlsx' ;
[num,txt,raw]  = xlsread(file) ;
phase = num(:,1) ;
amp = num(:,2) ;
loop = linspace(-10,10,length(num));
figure
subplot(211)
plot(loop,amp,'r')
ylabel('Aplitude')
subplot(212)
plot(loop,phase,'b')
ylabel('Phase Shift')
xlabel('loop')
