MATLAB: Is there a way to not replicate the preferences of MATLAB 7.1 (R14SP3) in the new installation of MATLAB 7.2 (R2006a)

MATLABprefdirpreference

I have installed MATLAB 7.2 (R2006a) on my machine, where MATLAB 7.1 (R14SP3) was previously installed. Unfortunately, I see that the preferences already chosen for R14SP3 are exactly replicated for R2006a. I would like to maintain the newest MATLAB installation with the default value of preferences, even if I have customized appearance, colors and fonts of the existing installation.

The ability to install MATLAB with default values of preferences when MATLAB 7.1 (R14SP3) is already installed is not available in MATLAB 7.2 (R2006a).

When you install R2006a, MATLAB creates a new preference folder and migrates the files in the R14SP3 preferences directory to the R2006a preferences directly.

To work around this issue, delete the contents of the preferences folder used by MATLAB 7.2 (R2006a). Note that the folder also contains files like history.m, which you do not have to delete. The preferences folder for R2006a is determined by running

 prefdir

in the MATLAB Command Window.

When you next start MATLAB 7.2 (R2006a), new preferences, the R2006a defaults, will be generated and stored.

The error is an XML error, so there is a problem with one of the saved status settings. Regenerating the preferences solves this issue.

To regenerate your MATLAB preferences, do the following:

1. Start MATLAB and type the following at the MATLAB command prompt:

prefdir

In MATLAB 7.0 (R14), the output should look like

     C:\WINNT\Profiles\{username}\Application Data\MathWorks\MATLAB\R14 (on Windows)
     /home/{username}/.matlab/R14 (on UNIX)
     /Users/{username}/.matlab/R14 (on Mac)

This is where your "matlab.prf" file is located. Your path may be different depending on how your system is setup.

2. Make sure that MATLAB is closed and rename the preferences directory of your current MATLAB version and all older versions of MATLAB to something else. For example, in MATLAB 7.0 (R14), rename the directory R14 to R14old. If you also have MATLAB 6.5 (R13) installed on your computer, rename the R13 directory to R13old.

3. Restart MATLAB. A new preferences directory will be created for the MATLAB version that is launched. Please note that the new preferences would be equivalent to the default preferences, including fonts, desktop layouts etc of a new installation of MATLAB.

If this does not address the issue that you hoped it would, it is possible to restore your preferences by deleting the newly created directories (R14 and/or R13) and renaming the R14old and/or R13old directories to their original names (R14 and R13 respectively).

MATLAB: How to make an axes transparent when using Plot Tools in MATLAB 7.1 (R14SP3) and MATLAB 7.2 (R2006a)

You can change the axes property “Color” to “none” by changing any of the RGB color values to NaN, as follows:

 1. Open Plot Tools
 2. Select the axes object
 3. Open the Property Inspector
 4. Expand the “Color” property to view the RGB components
 5. Change any RGB value to NaN

In MATLAB 7.2 (R2006a) it is not possible to make the axes transparent from the Plot Tools. To workaround this in MATLAB 7.2 (R2006a), use the SET command to change the axes property 'Color' to 'none'.

set(gca, ’Color’, ’none’)
