MATLAB: How to avoid this warning

guiguidematlab guioverwriting global constants

Hi, I have made a gui using GUIDE. When i call a function that is changing the path of matlab current directory. I get the following warning:
Warning: Function plot has the same name as a MATLAB builtin. We suggest you rename the function to avoid a potential name conflict.
> In gui>browse_Callback at 313 In gui_mainfcn at 96 In gui at 42 In @(hObject,eventdata)gui('browse_Callback',hObject,eventdata,guidata(hObject))
There appears also a warning upon startup of Matlab:
Warning: Function plot has the same name as a MATLAB builtin. We suggest you rename the function to avoid a potential name conflict. I have already tried this http://www.mathworks.com/matlabcentral/answers/215315-warnings-and-error-messages-after-launching-matlab-r2015a-for-the-first-time Thanks alot

This is most likely the problem:
path = strcat(path_choice);
path is a very important built-in global variable for MATLAB and you just destroyed it. Pick another name, like "folder" instead of "path". "folder" is okay to use.
Don't use cd() anyway - see the FAQ. Just construct a full filename with sprintf() and fullfile() whenever you need it and leave the current folder alone or you could have trouble later when you try to call functions that are no longer in the current folder.
