问题描述

我在Win32控制台应用程序中引入了从MATLAB生成的C ++共享库。 MATLAB程序需要2-3秒在MATLAB中执行，但控制台应用程序需要11-12秒执行。我读这是因为MCR的启动时间，我相信在MCR初始化后，它必须采取相同的时间，因为它需要matlab。那么如何加载或初始化MCR，以便它总是在RAM或缓存中，这样将需要2-3秒的控制台应用程序运行？我应该做一个无限循环，使MCR连续加载??我在Windows操作系统上工作，我从PHP调用控制台应用程序。任何教程或链接？

I incorporated C++ shared library generated from MATLAB in a Win32 console application. The MATLAB program takes 2-3 sec to execute in MATLAB but the console application takes 11-12 seconds to execute. I read this is because of the start up time of MCR and I believe after the MCR is initialized it must take same time as it takes in matlab. So how can I load or initialize the MCR so that it is always in the RAM or cache so that it will take 2-3 sec for the console application to run? Should I have to make an infinity loop so that the MCR is loaded continously?? I am working on Windows OS and I am calling the console application from PHP. Any tutorials or link for that?

我添加了MCR_CACHE_ROOT作为指向文件夹（非临时）的环境变量。我的控制台应用程序代码如下：

I have added the MCR_CACHE_ROOT as an environment variable which points to a folder(not temporary). My console application code is as follows:

// shoes_shared.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include "shoes_sharedlibrary.h"
#include <iostream>
#include <string.h>
#include "mex.h"



using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
    /* Call the MCR and library initialization functions */
 //const char *pStrings[]={"-nojvm","-nojit"};
 //   if (!mclInitializeApplication(pStrings,2))
 //   {
 //       fprintf(stderr, "Could not initialize MCR for the application.\n");
 //       return -1;
 //   }

if (!shoes_sharedlibraryInitialize())
{

    exit(1);
}



     mwArray img(argv[1]); 

     double wt1 = _tstof(argv[2]);
     mwArray C(wt1);
    double wt2 = _tstof(argv[3]);
    mwArray F(wt2);
    double wt3 = _tstof(argv[4]);
    mwArray T(wt3);
    double wt4 = _tstof(argv[5]);
    mwArray S(wt4);



           test_shoes(img,C,F,T,S);
            //shoes_sharedlibraryTerminate();
            //mclTerminateApplication();
            return 0;
}

我已经评论过上面的想法，它会使它更快，但没有运气。任何帮助？

I have commented the lines above thinking that it will make it faster but no luck. Any help?
