尝试在 Matlab 中使用发布时陷入无限循环

%Question 1 


y=dtmfsig(150006260); 

%a
t= linspace(0,0.9,7200) 
plot(t,y)
title('DTMF time signal')
xlabel('t (sec)') 
ylabel(' y(t)' ) 




% Part B

fLH= [697, 770, 852, 941, 1209, 1336, 1477] 


%Signal divided into 3 sections 
fs= 8000 
T=1/fs


y1= y(1:2400);     
y2=y(2401:4800); 
y3=y(4801:7200);


% Seven point DTFT 

Dy1= freqz(y1, 1, 2*pi*T*fLH);
Dy1n= abs(Dy1)

%   1



Dy2= freqz(y2, 1, 2*pi*T*fLH);
Dy2n= abs(Dy2)

%   3 

Dy3= freqz(y3, 1, 2*pi*T*fLH);
Dy3n= abs(Dy3)


% 2


% In each of these sections I used the given keypad to determine what my
% output would be based on the maximums in the matrix. I wrote what those
% numbers would be under each set of commands but to recap they are in
% order 1,3,2

%c  

t1= 600:1:1600 
 %First DTFT (Need to put points in Dy1n in) 
Dc1= freqz(y1, 1, t1.*2.*pi.*T)
Dc1n= abs(Dc1)
plot(t1, Dc1n./abs(max(Dc1n)))
title(' normalized spectrum of decode key 5') 
xlabel(' frequency (Hz) ')
ylabel(' magnitude') 


Dc2= freqz(y2, 1, t1.*2.*pi.*T)
Dc2n=abs(Dc2)
plot(t1, Dc1n./abs(max(Dc2n)))
title('normalized spectrum of decode key 3')
xlabel('frequency (Hz)') 
ylabel('magnitude')



Dc3= freqz(y3, 1,t1.*2.*pi.*T)
Dc3n=abs(Dc3) 
plot(t1, Dc1n./abs(max(Dc3n)))
title('normalized spectrum of decode key 8')
xlabel('frequency (Hz)') 
ylabel('magnitude')


% In this secion I computed the DTFT of the three segements that I divided
% the signal into and then graphed them. 


%d 

% For the last part of this question I created a table that shows the
% normalized values for the 3 different key values that are displayed in
% the graphs above
d= [fLH; Dy1; Dy2; Dy3]; 

fprintf('%6s  |  %10s %10s %10s\n', 'f', 'key 5', 'key 3', 'key 8') ; 
fprintf('-----|------------------------------------------\n'); 
fprintf('%6.d| %10.3f %10.3f %10.3f\n',d); 

publish('lab2question1.m','pdf')

每当我发布此内容时，我都会陷入一个弹出的数字循环中，除非我单击 ctrl+c ，否则不会停止......有关如何解决此问题的任何建议吗？我正在尝试创建一个 pdf 文件，其中包含我放入此代码中的所有图表和注释。第一次使用发布，当我查看 matlab 中发布命令的帮助函数时，似乎我做得正确。

命令publish executes给定名称的脚本，并记录输出。您的错误是将此命令插入到脚本本身中。这会导致无限循环：脚本运行，然后在最后遇到publish命令，这意味着它必须再次运行，所以它执行了，然后遇到publish, etc.

你应该调用

publish('lab2question1.m','pdf')

来自命令窗口，而不是来自脚本本身。
