Command Window, display line numbers?

Hi. Is it possible to make matlab print line numbers in the command window? like;

Thanks!

1   %something%
2   %something%
3   %something%

Hi Joshua,

There is no method to configure command window in such a manner that the line number is shown corresponding to every line in output automatically, but you can achieve that my printing the line numbers on your own using the manual script. Here’s an example code to achieve that –

output = {
    "%something%",
    "%something%",
    "%something%"
};

% Loop through each line and print with line numbers
for i = 1:length(output)
    fprintf('%d: %s\n', i, output{i});
end

Hope this is what you were trying to achieve.

In a fairly limited sense:

You can get line numbers of a file that you are displaying. Use dbtype . For example

dbtype which.m

1     %WHICH  Locate functions and files.
2     %   WHICH ITEM displays the full path for ITEM. ITEM can include a partial
3     %   path, complete path, relative path, or no path. ITEM must be on the 
4     %   search path or in the current folder.
5     % 
6     %   If ITEM is a Simulink model, a MATLAB app file, or a MATLAB function or 
7     %   script in a MATLAB code file, then WHICH displays the full path for the 
8     %   corresponding file.
9     % 
10    %   If ITEM is a method in a loaded Java class, then WHICH displays the
11    %   package, class, and method name for that method.
12    % 
13    %   If ITEM is a workspace variable, then WHICH displays a message
14    %   identifying ITEM as a variable.
15    %   
16    %   If ITEM is a file name with a specified extension, then WHICH displays 
17    %   the full path of ITEM.
18    %
19    %   If ITEM is an overloaded function or method, then WHICH ITEM returns
20    %   only the path of the first function or method found.
21    % 
22    %   WHICH FUN1 in FUN2 displays the path to function FUN1 that is called by
23    %   file FUN2. Use this syntax to determine whether a local function is
24    %   being called instead of a function on the path. This syntax does not
25    %   locate nested functions.
26    % 
27    %   WHICH ___ -ALL displays the paths to all items on the MATLAB path with
28    %   the requested name. Such items include methods of instantiated classes.
29    %   You can use -ALL with the input arguments of any of the previous
30    %   syntaxes.
31    % 
32    %   S = WHICH(ITEM) returns the full path for ITEM in the character vector, S.
33    % 
34    %   S = WHICH(FUN1,'IN',FUN2) returns the path to function FUN1 that is
35    %   called by file FUN2. Use this syntax to determine whether a local
36    %   function is being called instead of a function on the path. This syntax
37    %   does not locate nested functions.
38    % 
39    %   S = WHICH(___,'-ALL') returns the results of WHICH in the character vector or
40    %   cell array of character vectors, S. You can use this syntax with any of the input
41    %   arguments in the previous syntax group. Each row of cell array S
42    %   identifies a function. The functions are in order of precedence, unless
43    %   they are shadowed. Among shadowed functions, you should not rely on the
44    %   order of the functions in S.
45    %  
46    %   For more information about function precedence order, see the MATLAB
47    %   documentation.
