About Compile Function

Question

I have a function that take p as a parameter, p is a 2X3X3 list,

( a 2X3X3 list can like { {{2,3},{1,2.},{1,1.}}, {{2,3.},{1,2},{1,1}}, {{2,3},{1,2},{1,1}} } )

the function just as:

func[p_]:= Module[{}, {Main Fuction} ];

If I want to use Complie Function:

func= Compile[{p,_Real,???},
Module[{}, {Main Fuction} ]
];

How do I define ??? (above)

Try and read your own question to see if it is clear enough, because I have hard time understanding it. — Sektor, Jul 25 '14 at 11:14
Considering the code you showed in your previous question, I want to remind you that Compile isn't a panacea for speed, it'll lead to more limitation in programming and may bring you endless grief indeed. Have you already read this and this post? — xzczd, Jul 25 '14 at 11:48
@ xzczd, You are so clever, I just want to add a Compile Function to speed up my code, But found it cannot..... — YuYong, Jul 25 '14 at 11:51
Well, you should not place a space between "@" and my name, or I won't get the reminder. — xzczd, Jul 25 '14 at 11:57

enter image description here

{ {{2,3},{1,2.},{1,1.}}, {{2,3.},{1,2},{1,1}}, {{2,3},{1,2},{1,1}} } // TensorRank

Therefore:

cfn = Compile[{{p, _Real, 3}}, Plus @@@ p];

{{{2, 3}, {1, 2.}, {1, 1.}}, {{2, 3.}, {1, 2}, {1, 1}}, {{2, 3}, {1, 2}, {1, 1}}} // cfn

{{4., 6.}, {4., 6.}, {4., 6.}}

If you are using an older version of Mathematica use ArrayDepth instead.
