How do I avoid this error "undefined function or variable 'matlabpool'"?

I use matlab 2017a and whenever I use parfor function it gives me the error "undefined function or variable 'matlabpool'". I have a dual core i5 processor and the parallel computing toolbox works fine and connects to two workers when I start Parallel computing. But when I write a function or use parfor it gives me error "undefined function or variable 'matlabpool'". What should I do?

Replace "matlabpool" with "parpool" everywhere in your code.
