The commands 'implay' and 'VideoReader' weren't executing due to an error in the configuration file. I re-installed MATLAB thinking it would be overcome. But, it didn't. How can this be solved?

The warning goes as given below:

Warning: Function load has the same name as a MATLAB builtin. We suggest you rename the function to avoid a potential name
conflict. 
Warning: Invalid configuration file.

I'd start with using the debugger to find out, which config file is meant:

dbstop if warning

Then renaming the config file might help, when Matlab re-creates is automatically. If not, deleteing the file and a re-installation of Matlab might help.
