有人知道如何找到哪个函数向Maltab中的命令窗口提供输出吗?我已经编写了具有许多功能的代码，已经将输出输出到命令窗口，但是我找不到负责该功能的函数.谢谢！

does anyone knows how to find which function is providing output to the command window in Maltab? I've written a code with many functions, I have output to the command window but I can't find which function is responsible for that. Thanks !

推荐答案

如果所有输出均由您自己的代码打印，则可以轻松地将所有fprintf和disp调用替换为您自己的函数调用，这些函数调用可以为所有输出加上前缀函数名称.

If all output is printed by your own code, you can easily replace all fprintf and disp calls with your own function calls that optionally prefix all output with the function name.

代码如下:

getfunctionname.m:

getfunctionname.m:

function [CurrentFunctionName, PreviousFunctionName] = getfunctionname()
CurrentFunctionName = '';
PreviousFunctionName = '';
MyStack = dbstack('-completenames');
if (length(MyStack) < 2)
    error('Function getfunctionname.m cannot be called from MATLAB console.');
elseif (length(MyStack) == 2)
    CurrentFunctionName = MyStack(2).name;
else
    CurrentFunctionName = MyStack(2).name;
    PreviousFunctionName = MyStack(3).name;
end
return

myprintf.m:<​​/p>

myprintf.m:

function myprintf(varargin)
global PrefixOutputWithFunctionName
if (PrefixOutputWithFunctionName)
    [~, PreviousFunctionName] = getfunctionname;
    fprintf('### %s.m:\n', PreviousFunctionName);
end
disp(sprintf(varargin{:}));
return

mydisp.m:

function mydisp(varargin)
global PrefixOutputWithFunctionName
if (PrefixOutputWithFunctionName)
    [~, PreviousFunctionName] = getfunctionname;
    fprintf('### %s.m:\n', PreviousFunctionName);
end
disp(varargin{:});
return

mainfunction.m:

mainfunction.m:

function mainfunction()
global PrefixOutputWithFunctionName

% set PrefixOutputWithFunctionName to false to disable prefixing.
PrefixOutputWithFunctionName = true;

% the code goes here...

% example output.
myprintf('some text...\n some more text...');
return
