Share your code along with a description of what you were doing that resulted in these errors.

There are two main possibilities:
- something on your path, third party code or your own function, has the same name as a function that matlab relies on; or
- somehow, on a case-insensitive file system, a file got created with the wrong case. For example the file came out myclass.m to define the class MyClass . MATLAB places the call asking for MyClass and the case-insensitive file system thinks surely myclass.m is the same file, but then MATLAB checks what it got back and says "Wrong file!"
In the first situation try
restoredefaultpath; rehash toolboxcache
and cd to a directory with no matlab files. If it starts working then you know that something on the path is the problem.
In particular if you have SPM installed, it has some capability directories that include functions that interfere with MATLAB.
