Hi,
Everything worked fine before I created my first script and stored it in another folder and tried to run it. Then I could not run anything. The system is Win 8.1 64bit. I re-installed, nothing changed. Here's the message:
Warning: MATLAB did not appear to successfully set the search path. To recover
for this session of MATLAB, type "restoredefaultpath;matlabrc". To find out how
to avoid this warning the next time you start MATLAB, type "docsearch problem
path" after recovering for this session.
Warning: Initializing Java preferences failed in matlabrc.
This indicates a potentially serious problem in your MATLAB setup, which should
be resolved as soon as possible. Error detected was:
MATLAB:UndefinedFunction
Undefined function 'usejava' for input arguments of type 'char'.
> In matlabrc (line 121)
Warning: Initializing MATLAB Graphics failed.

You need to rename
C:\Users\Zhengye Bian\Documents\MATLAB\feature.m
to not be named 'feature.m', or move it out of your MATLAB path.
You might also need to remove your preferences directory; https://www.mathworks.com/help/matlab/ref/prefdir.html or your startup.m

hi,
As soon as you open Matlab, run this command at command prompt and then proceed further
restoredefaultpath;matlabrc
