Nitin - you are changing the MATLAB search path when doing
path('some_random_folder')
Since you are specifying a new folder, you are losing all of the default (and other) folders that the MATLAB search path included previously. So you won't be able to run any of the MATLAB built-in functions or any of your functions.
To see all of the information that you are losing, type
path
and something similar to the following will appear
/Applications/MATLAB_R2014a.app/toolbox/matlab/demos
/Applications/MATLAB_R2014a.app/toolbox/matlab/graph2d
/Applications/MATLAB_R2014a.app/toolbox/matlab/graph3d
/Applications/MATLAB_R2014a.app/toolbox/matlab/graphics
/Applications/MATLAB_R2014a.app/toolbox/matlab/plottools
/Applications/MATLAB_R2014a.app/toolbox/matlab/scribe
/Applications/MATLAB_R2014a.app/toolbox/matlab/specgraph
/Applications/MATLAB_R2014a.app/toolbox/matlab/uitools
/Applications/MATLAB_R2014a.app/toolbox/local
etc.
(The above is from R2014a, OS X 10.8.5.)
If you wish to add a new folder to the MATLAB search path, then just do
path(path,'some_random_folder');
