如何根据MATLAB中的条件从中间开始运行脚本？

Question

我有一个脚本需要花费大量时间才能运行，并且生成的一些结果可能不太令人满意，我们可能需要重新运行部分脚本。

所以我已经选择了在需要的地方退出程序并将所有工作区变量保存到文件中。但是当用户稍后再次运行脚本时，我不希望脚本从头开始运行。我想询问用户他们已经取得了多大进展，并且从那里继续。

一个可能的解决方案是使用goto，这在MATLAB中是不存在的（如果我能避免的话，我个人不喜欢使用它）。还有其他可能的解决方案吗？

我的脚本基本上结合了很多其他脚本。我想让用户选择从哪个脚本开始。如果需要，这是代码： -

clear all;
close all;
clc;

disp('This is a script to do the back projection for an event given the required input files.');
disp('Please make sure you have copied all of the following files into the ./back_projection/data directory:-');
disp(' ');
disp('1. V_{array}.txt - File containing the velocity data of all the stations selected from the array in one single column');
disp('2. T_{array}.txt - FIle containing the corresponding time data for rall the stations selected from the array in one single column');
disp('3. P_time_{array} - File containing the P wave arrival time of the event at all all the selected stations of the array');
disp('4. stnlat_{array} - File containing the station latitudes of all the stations selected from the array');
disp('5. stnlong_{array} - File containing the station longitudes of all the stations selected from the array');
disp('6. data_info_{array}.txt - File containing the GCARC, AZ and BAZ of the event at all the stations selected from the array');
disp(' ');
input('Continue? (After making sure, press enter)','s');

%% Starting back projection

Answer 1

按照

的方式做点什么

c = input('Which script?');
switch c
case -1
    % first script
case 0
    % second script
case 1
   % third Script
otherwise
   % fourth script
end

如果你不这样做，你也可以在Matlab中阻止注释一些代码。
