The error message tells you what to do. diag() is a function; [1 2 3] is a vector, so:
diag([1 2 3])

The syntax for calling functions is function name followed by ( followed by a list of parameters followed by )
You are trying to use diag[Expressions] -- which would be the kind of calling syntax that Mathematica would use, but not MATLAB.
Use diag([Expressions]) instead.
