Help with large start up error R2014a.

I receive a long list of errors upon start-up of Matlab:

I've reinstalled and updated JDK which hasn't helped.

I'm running Windows 8.1 with R2014a 64bit.

Has anyone else had this problem or know a solution?

Did you try

    >> which workspacefunc -all

which should return something like

    C:\...\MATLAB\R2013a\toolbox\matlab\codetools\workspacefunc.m

Using

>> which workspacefunc -all

gives back

'workspacefunc' not found.

[per isakson]

"'workspacefunc' not found." &nbsp The Matlab search path is corrupted.

First, read the documentation on the search path. Start at What Is the MATLAB Search Path?

Then run

    savepath

and next run

    restoredefaultpath

But before that make sure you understand. Or wait for a better answer.

I think the problem is much deeper than it looks. I cannot even attempt to set paths without unknown function error coming up. I have found this is also the case for nearly every other inbuilt Matlab function even the command 'ver'. Most of the options in the menus return unknown function as well.

It looks like the install isn't setting up the correct file paths for some reason.

As a test I have installed the the 32 bit version of Matlab R2014a and it works perfectly. I have no idea why the 64bit version crashes but as long as I've got a working version of Matlab I'm happy.

Thanks for your time and help, ill have another go at the 64bit when I have the time and patience.

You may want to try the following commands

rehash
rehash toolboxcache

[Mathew]

Tried both

rehash
rehash toolboxcache

Same outcome.
