Yes, but it's not the same way. I don't use Matlab, but I do use

But Mathemtica resolved this problem better than Matlab. In Mathematica,
system commands and symbols all start with Uppercase, and in addition,
they can not be overwritten explicity.
try to define a function which is allready a system function, and will
get an error:
Sqrt[x_]:=x^(1/2)
....
Sqrt[x_]} is Protected.
Unprotect[Sqrt]
Sqrt[x_]=x^3
