How to use DIR function

I'm using this code:
MatFileDirectories = MatFileDirectories(1)
MatFileDetails = dir(MatFileDirectories)
but I get this error:
_??? Error using ==> dir
Function is not defined for 'cell' inputs._
Mat file directories is an array containing all the drive paths of the mat files:
MatFileDirectories = {
I don't get why it can't read the path from the array

Common mistake, use braces instead of parentheses:
MatFileDirectories = MatFileDirectories{1};
In general, anytime you have problems with cell arrays, switch from () to {}, or from {} to (). Chances are, one of them will work. Another useful tip is to learn about the cell2mat() and char() functions.
