matlab GOTO（排序） [英] matlab GOTO (sort of)

问题描述

为了进行调试，我认为如果在点击一个文件时会很有用图片 - 编辑器到一个特定的行。有人知道这是否可以？

我以为我可以实现像

  A = []; 
 figure 
 plot（x）
 
 A = ginput（1）
 
如果A〜= [] 
 goto（指针，行）
 end 
  

问题是，只有在数字是制作。不是在分析结束时，我看看最终错误的数字。

换句话说：有没有办法去一个特定的行代码点击数字？

NB有关GOTO的实现，请参见（ GOTO FileExchange ）

解决方案

尝试使用 opentoline 函数与回调结合使用。像

  plot（1:10）; ％一个简单的图
 set（gcf，'ButtonDownFcn'，@（h，e）opentoline（'YourFunctionName.m'，LineNumber））; 
  

在这种情况下，当您点击图（而不是轴，或任何标签，但是m文件将在编辑器中打开指定的行。

如果要以编程方式确定行号，请执行以下

  plot（1:10）
 st = dbstack; 
 set（gcf，'ButtonDownFcn'，@（h，e）opentoline（st（1）.file，st（1）.line-1））; 
  

I have a long script calling many other scripts that spit out a lot of figures.

For debugging purposes I think it would be useful if -when clicking on a picture- the editor goes to a specific line. Does anyone know if this is possible?

I thought I could implement something like

A=[];
figure
plot(x)

A=ginput(1)

if A~=[]
  goto(pointer,line)
end

The problem is that it only would work only right after that the figure is made. Not at the end of the analysis when I take a look to the figures for eventual errors.

In other words: is there a way to go to a specific line of the code by clicking on a figure?

N.B. For an implementation of GOTO see (GOTO FileExchange)

解决方案

Try using the opentoline function in conjunction with a callback. Something like

plot(1:10); % A simple plot
set(gcf,'ButtonDownFcn',@(h,e)opentoline('YourFunctionName.m',LineNumber));

In this case, when you click on the figure (not the axis, or any labels, but the grey part of the figure) the m file will open in the editor to the line specified.

If you want to programmatically determine the line number then do the following

plot(1:10)
st = dbstack;
set(gcf,'ButtonDownFcn',@(h,e)opentoline(st(1).file,st(1).line-1));
