Some Toolboxes Not Viewable in Matlab

After installing Matlab successfully you find that some of the toolboxes are not available in the Start > Toolboxes list. The problem lies with incorrect paths. To fix this follow the steps below.

Execute the following command in Matlab
```
restoredefaultpath
```
Execute the command:
```
savepath
```
- If that command fails it is because you don't have write permission to the install directory (for example /opt/MatlabR2009a/toolbox/local/). Run this instead:
```
savepath pathdef.m
```
Copy or move the file pathdef.m from your Matlab working directory to the install directory /opt/MatlabR2009a/toolbox/local/.
Now when you run the command ver all the correct toolboxes should be listed and they should be accessible from within Matlab.
