You can turn the message off with the Off command.


However, there is more than one type of error that can occur. A better 
method might be to error check with function overloading.

If the arguments are of the right type, use the compiled function.

RealQ[x_] := MatchQ[x, _Real]

f2[arg1_/;MatrixQ[arg1, RealQ], arg2_Real, arg3_Real] :=
   f[arg1, arg2, arg3]

Otherwise, use the uncompiled function.

f2[arg1_, arg2_, arg3_] :=
