Ошибка при создании файлов C mex в Matlab: разрешение отклонено

Я попытался скомпилировать код C в Matlab.

Я тестировал простой пример кода в подпапках matlabroot/extern/examples. Я сделал следующее:

mex -setup
copyfile(fullfile(matlabroot,'extern','examples','mex', 'yprime.c'), './');
mex -v -g yprime.c

Командная строка выводит следующую информацию, которая, я думаю, должна быть проблемой пути, но я не знаю, как ее решить.

 Warning: Neither -compatibleArrayDims nor -largeArrayDims is selected. 
           Using -compatibleArrayDims. In the future, MATLAB will require
           the use of -largeArrayDims and remove the -compatibleArrayDims
           option. For more information, see:
