MATLAB: After installing Matlab R2017a on Ubuntu I cannot set the path. I get the error “Undefined function or variable ‘pathtool’

matlab r2017aUbuntu

– When I click on "Set Path" I get the message "Undefined function or variable 'pathtool'". If I type "path" at the prompt I get a long list with paths, so it seems the path is ok – What can I do?

Best Answer

Execute the following statements in MATLAB to resolve this issue:

>> restoredefaultpath

>> rehash toolboxcache

>> savepath

Please note that this will restore MATLAB to default paths, removing custom added paths.

For performance purposes, MATLAB caches a list of files on the MATLAB search path (including toolbox files), and this cache can persist even after closing MATLAB (but not after restarting your machin). It seems that this cache is getting into a bad state on your machine.

Try the following commands:

restoredefaultpath
rehash toolboxcache
savepath

If the above fails to resolve the issue, try restarting your system.

MATLAB: Efficient way to display a walked path.

Assuming you have the (x,y) coordinates of the path, just use plot() and pick a really wide line width.

plot(x, y, 'LineWidth', 10);
