MATLAB Central Newsreader - Matlab path issues

Re: Matlab path issues

Thanks for your help.

However, the problem I now have is something like this:

1. I have a statement

if ~isdeployed

...do normal actions

else
try
a=which('file.xls')
xlswrite((fileparts(a),'\file.xls'),options)
end
end

I have realised the main problem is with the Which function.

Running the application via Matlab gives no problems. But
running the deployed function with which looks ONLY in the
CTF archive folder - as file.xls is not located there, the
application stops.

I know I can add MAT files to the archive, but XLS not.

There must be a way for the deployed application to find a
file anywhere on the path and provide the correct location
text?

Any ideas
Thanks
Matt

Hi Matthew,
Could you read my reply clearly?
I guess the file 'file.xls' has a fixed relative path to the deployed function (exe)?
If so, as long as you know the path (APP_PATH) of the deployed function (exe) then you can directly get the path of you xls file ([APP_PATH, relativepath]). And you DO NOT 'which' function any more...

Hi Bill,

Yes, I figured that one out.

Now I compile something like this:

mcc -m file.m -a file.xls

This works, but I am having a problem with some graphic
files. I have about 50 photographs in a folder called
Photos. These cannot be used (found on path) by deployed
function. So I tried:

mcc -m file.m -a file.xls -a C:/Programme.../Photos

Then executed the executable to create the CTF and looked
in the folder in the mcr folder (Photos) and its empty.

According to the help -a ./Folder, should add all files
located in that folder. Does not seem to work.

Cheers
Matt

Hi Matt,
Depends on your requirment. If the data file is fixed, and you do not want to hide your files or not.
1. If you want to hide the files, you can use mcc ... -a \.path to add the whole folder to you achieve. Only one exe in your prject.
2. In any case, if you want to handle your folder visibly. I.e. output data. You can add a folder to the relative path the application. exe + files/folders.

Matlab path issues

Matthew Wade — Mon, 18 Aug 2008 10:13:03 -0400

Hi,

I have an application (GUI) that also is compiled as a
stand-alone executable to be run on other machines.

1. The GUI has some functions that require data to be
saved/called from specific paths, e.g.
C:/Matlab7.1/work/Results

2. To ensure the data is stored in the correct folders, I
use cd pathname, or xlswrite('pathname',data), for example.

3. For some time, I was able to specify the pathname as
only /Results, and this enabled flexibility - now I get
error messages (unknown directory) and cannot trace back
the problem - I now have to use the complete pathname.

4. When I install the stand-alone executable on a new
machine, the problem will occur that I do not have the same
pathname as on the host computer, so when the script cd or
xlswrite is executed with a specifie path, there will be an
error.

Can anyone think of a way to specify folders/directories
that can be generic to any machine? e.g. a function that
creates a folder "Results" in a common and sensible
location (i.e. the Program location f?r the executable and
the work folder for the original -m files).

Thanks
Matt

Hi
To me I always use the global variable.
Add these code to the main function, and you can use the relative path base on the root dir.
global APP_ROOTDIR ;
APP_ROOTDIR = which('APP_Start') ;
CWIND_ROOTDIR = fileparts(APP_ROOTDIR) ;
if isempty(APP_ROOTDIR)
warning('Please change directory to the root, then start it again.') ;
return ;
else
end

Also, use filesep instead / or \ in case you wish to run it on both
Windows and Unix.

May be this anwsers your question:

With the command 'pwd' you get the path to the directory where the application.exe resides.

For sometime I use a function similar to this to return the path of my application:

function pname=APP_path(varargin)

thisfile=mfilename('fullpath');
[pname] = fileparts(thisfile);
if isdeployed
    for upstep=1:2
        pos=find(pname==filesep, 1, 'last');
        pname=pname(1:pos-1);
    end
end

[pname] = strcat([pname filesep],varargin{:});
