I use Matlab2012b,and I want to use toolbox from power system analysis book.
I create a subdirectory, "power", where the MATLAB toolbox resides.I copy the book's toolbox files to c/program/matlab/r2010b/toolbox/power.
I open any file, but it occurs like the following error:
Cannot find an exact (case-sensitive) match for 'ChP1EX1.m'
The closest match is C:\Program Files\MATLAB\R2012b\toolbox\power\ChP1EX1.M
To change the file extension, cd to the file's folder, type: movefile ChP1EX1.M ChP1EX1.m_bad; movefile ChP1EX1.m_bad ChP1EX1.m and then cd back.
Can someone help me how to open the file correctly??

cd to the file's folder, type: movefile ChP1EX1.M ChP1EX1.m_bad; movefile ChP1EX1.m_bad ChP1EX1.m and then cd back
just like it says on the box :-)

Or:
movefile('C:\Program Files\MATLAB\R2012b\toolbox\power\ChP1EX1.M', ...
'C:\Program Files\MATLAB\R2012b\toolbox\power\ChP1EX1.m');
Afterwards a rehash toolboxcache command might be required, when you really want to add files inside Matlab's root folder.
[EDITED] Windows is sometimes too dull to work as wanted. Perhaps an intermediate step is required:
movefile('C:\Program Files\MATLAB\R2012b\toolbox\power\ChP1EX1.M', ...
'C:\Program Files\MATLAB\R2012b\toolbox\power\ChP1EX1.m_');
movefile('C:\Program Files\MATLAB\R2012b\toolbox\power\ChP1EX1.m_', ...
'C:\Program Files\MATLAB\R2012b\toolbox\power\ChP1EX1.m');

Cannot find an exact (case-sensitive) match for 'barcycle.m'
The closest match is C:\Users\Kashif Javed\Downloads\Compressed\Matlab_tool_box\Matlab tool box\Folder 1\BARCYCLE.M
To change the file extension, cd to the file's folder, type:
movefile BARCYCLE.M BARCYCLE.m_bad; movefile BARCYCLE.m_bad BARCYCLE.m and then cd back.

Follow the instructions in the error message.
To change the file extension, cd to the file's folder, type:
movefile BARCYCLE.M BARCYCLE.m_bad; movefile BARCYCLE.m_bad BARCYCLE.m and then cd back.
That will involve four commands:
  1. cd into the file's folder.
  2. movefile BARCYCLE.M BARCYCLE.m_bad;
  3. movefile BARCYCLE.m_bad BARCYCLE.m
  4. cd back to the folder you were in previously

把文件ChP1EX1.M后缀大写改为小写ChP1EX1.m即可

I try movfile ('C:\Program Files\MATLAB\R2012b\toolbox\power\ChP1EX1.M); error : access denied.
Then, I see this: http://www.mathworks.com/help/matlab/matlab_env/toolbox-path-caching-in-the-matlab-program.html
I also update toolbox path cache, but I still don't have access to run any file in the toolbox.
other suggestions?

The shown command cannot work: A quote and the complete destination is missing. Please post a copy of the code you use, otherwise we cannot guess, what you are exactly trying to do.
The error message sounds like the currently active user do not have write access to this folder. So either login with an admin account or let the admin modify the file access permissions for this folder. But when an admin is already active, ask him for changing the ".M" to ".m" manually, because this is most likely faster than running the renaming from Matlab.

I don't have the access to save and edit in the C:\Program Files\MATLAB\R2012b\toolbox location.
if someone know how to change the permission to all the files??

You need to be administrator to do that.
You are probably using a newer version of Windows in which everything in \Program Files\ is protected against user modification.

It seems like admin privileges are used already. But this might be a bad idea.

Yo tambien estaba ensayando el codigo del profesor Hadi Saadat, y tenía el mismo problema de @CHIYUAN.
Lo solucioné de la siguiente manera. Abrí el archivo independiente, ejemplo "ZBUILD.M" y lo volví a guardar como "zbuild.m", luego de eso inicíe la función y le dí "movefile zbuild.M zbuild.m_bad; movefile zbuild.m_bad zbuild.m " en el Command Window. Luego volví a invocar la función y funcionó. Espero le sirva
