MATLAB: Does the MATLABRC file get echoed to the command window when I start MATLAB

My MATLABRC file gets echoed to the command window when I start MATLAB.

Best Answer

This problem usually occurs if you have the ECHO feature turned on.

Go to File menu --> Preferences and make sure the "echo on" option is NOT checked off. As of MATLAB 6.0, this option is located in the Command Windows Preferences. In MATLAB 5.3 and earlier, it is located on the General Preferences tab.

The same can also be achieved by putting the following statement in startup.m:

echo off

MATLAB: Do I get an “undefined function” error and loss of command functionality when I start MATLAB

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

This issue is due to a corrupt pathdef.m file, which contains a list of the directories in the MATLAB search path.

To resolve this issue, see the following:

If you are using MATLAB 7.0 (R14), type the following commands:

restoredefaultpath ; matlabrc

If this command resolves the issue, type the following command to save the current path for all future sessions of MATLAB:

savepath

If you are using versions of MATLAB prior to MATLAB 7.0 (R14), follow the appropriate instructions below:

For Windows Installations

Start MATLAB, and enter the following commands:

matlabpath(char(com.mathworks.jmi.MatlabPath.getDefaultPath))
path2rc(fullfile(matlabroot,'toolbox','local','pathdef.m'))

This will regenerate your pathdef.m file.

If you still have problems, send a copy of your pathdef.m file from $MATLAB/toolbox/local/ to support@mathworks.com and mention Solution 1-1AVEG in the subject field.

MATLAB: Do I get the error message “Undefined function or method ‘javachk’ for input arguments of type ‘char'” when I start MATLAB

This issue may indicate a problem with the MATLAB path. Execute the following commands in the MATLAB Command Window to reset the path to the default settings:

restoredefaultpath; matlabrc
savepath

After running these commands, restart MATLAB.
