matlab - 在 switch-case MATLAB 中执行多个案例

Question

我想根据用户输入转到脚本的特定部分，然后从那里继续并执行整个脚本。我尝试使用 switch case 来实现它，但问题是在 matlab 中的 switch case 中，当我们没有显式调用break时，不会陷入下一个情况。但我的程序逻辑是，我需要转到一个案例，并执行之后的所有案例，包括该案例。如何在 MATLAB 中实现这一目标？

这是我的脚本供引用:-

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');

我的首选方法是将代码分成函数(可能是 local functions 甚至 private functions ，这具有额外的优点，这使得代码更具可读性，然后让每个函数在其末尾，它在返回之前调用序列中的下一个函数。

这将准确地创建您想要的级联，并且在主脚本中，您只需要一个 switch 语句来为“级联”中的特定步骤调用适当的函数。

例如:

function main_function(Input)
  switch(Input)  % assumes appropriate Input checks and sanitization has occured
    case 1; step1_generate_grid();
    case 2; step2_station_check();
    case 3; step3_cross_correlation();
    case 4; step4_etc_etc();
    otherwise; disp('Nothing to perform');
  end
end

function step1_generate_grid()
  disp('Generating Grid...');
  step2_station_check(); % Go to next step in cascade
end

function step2_station_check()
  disp('Checking station...');
  step3_cross_correlation(); % Go to next step in cascade
end

function step3_cross_correlation()
  disp('Performing cross-correlation...');
  step4_etc_etc(); % Go to next step in cascade 
end

function step4_etc_etc()
  disp('Performing final steps etc...');
  % Final step in cascade, no further functions to call.
end
