Question

我想编译一个我创建的自定义函数，以加快计算时间，这已经很小了，但是我把这个函数称为“几次”。

一些虚拟数据：

DD = 20; Days = 4; Peak = 1;
Loading = 
Table[Table[{RandomReal[{-1500, 1500}], 
RandomReal[{-1, 1}/100]}, {i, 1, 150}], {j, 1, Days}];
coo = Loading[[All, All, 1]];

功能：

Clear[TimeSwapFunctionTEST];  
TimeSwapFunctionTEST[lst_ /; (And @@ (NumericQ /@ lst))] := 
Norm[With[{z = 
 Sort[Partition[
   Flatten[Riffle[Flatten[coo + lst], 
     Flatten[Loading[[1 ;; Days, All, Peak + 1]]]]], 
   2], #1[[1]] < #2[[1]] &]},
Mean[Select[
  Partition[
   Riffle[Mean[Transpose[Partition[z[[All, 1]], DD]]], 
    Abs[Mean[
       Transpose[
        Partition[z[[All, 2]], DD]]]/(StandardDeviation[
         Transpose[Partition[z[[All, 2]], DD]]]/Sqrt[DD])]], 
   2], #1[[1]] > 0 &][[All, 2]]]]]

一千次射击的计算时间约为6“

AbsoluteTiming[Do[TimeSwapFunctionTEST[{0, 0, 0, 0}], {i, 1, 1000}]]
{6.0323450, Null}

我已经尝试了但是我对参数lst_ /; (And @@ (NumericQ /@ lst))有一些问题所以我必须删除它（但我最后会需要它）。所以如果我试过这个：

Clear[TimeSwapFunctionTESTCompiled];
TimeSwapFunctionTESTCompiled = 
Compile[{{lst(*/;(And@@(NumericQ/@lst))*), _Real}}, 
With[{x = 
 Sort[Partition[
   Flatten[Riffle[Flatten[coo + lst], 
     Flatten[Loading[[1 ;; Days, 1 ;; -1, Peak + 1]]]]], 
   2], #1[[1]] < #2[[1]] &]},
Mean[Select[
  Partition[
   Riffle[Mean[Transpose[Partition[x[[All, 1]], DD]]], 
    Abs[Mean[
       Transpose[
        Partition[x[[All, 2]], DD]]]/(StandardDeviation[
         Transpose[Partition[x[[All, 2]], DD]]]/Sqrt[DD])]], 
   2], #1[[1]] > 0 &][[All, 2]]]]]

我收到了这些错误：

Compile::part: Part specification Compile`FunctionVariable$25889[[All,2]] cannot be     compiled since the argument is not a tensor of sufficient rank. Evaluation will use the     uncompiled function. >>
Compile::cplist: Compile`$5 should be a tensor of type Integer, Real, or Complex;    evaluation will use the uncompiled function. >>

你有什么想法来编译吗？感谢
