Undefined function 'copy' for input arguments of type 'double'.

Undefined function 'copy' for input arguments of type 'double'.' And I tried to find function 'copy' path.There are too many named 'copy.m' in the matlab root path. And I commanded 'which copy',It answered ' copy is a built-in method % schema.package method'.

what's more,I reinstalled matlab, It didn't work. How can I resolve the problem? thks.

Hi Frank,

I understand that you are facing the error 'Undefined function 'copy' for input arguments of type 'double''.

The following workarounds will help you in resolving this issue-

1. At first please double-check the output of:

>> which -all copy

and check if any overloaded function is showing up. If yes, move this function aside the search path or use:

>> restoredefaultpath
>> rehash toolboxcache
>> savepath

2.If this is not the case/does not help, It could be that the Model Advisor Cache is corrupt and this causes it. To resolve it, please simply run:

>> Advisor.Manager.refresh_customizations()

I hope this helps!

Hi Atharva,

I remove all overloaded functions named 'copy.m' from the search path. And it does work！

Thank you very much! you are so kind man!
