编辑：谢谢，对那些感兴趣的人的固定代码：ert_main.cpp：

#include /* This ert_main.c example uses printf/fflush */

#include "Rx.h" /* Model's header file */

#include "rtwtypes.h" /* MathWorks types */

#include

#include

#include

#include

#include

#include

//#include //for writing results to file

//#include //doesn't work

#include

#define lengthOFSignal 5000

在主要功能上：

using namespace std;

std::vector<:string> words;

std::string word;

ifstream iFile;

string path = __FILE__; //gets source code path, include file name

path = path.substr(0,1+path.find_last_of('\\')); //removes file name

string testFileName = "LEGACY_R12_800BITS_40MHz.dat";

path+= testFileName; //adds input file to path

int signal_length=0;

std::vector real_part_VEC, imag_part_VEC;

std::istringstream ss;

real_T real_temp, imag_temp;

iFile.open(path,ios::binary );

//iFile.open(path.c_str(), ios::binary);

if (iFile.is_open()) {

while (std::getline(iFile, word)) {

words.push_back(word);

}

iFile.close();

}

signal_length=words.size();

for(int i=0; i< signal_length;i++)

{

ss.str(words[i]);

ss >> real_temp >> imag_temp;

real_part_VEC.push_back(real_temp);

imag_part_VEC.push_back(imag_temp);

}

real_T real_part[lengthOFSignal];

real_T imag_part[lengthOFSignal];

for (int i=0; i < signal_length; i++) {

real_part[i]=real_part_VEC[i];

imag_part[i]=imag_part_VEC[i];

}

/* Initialize model */

Rx_initialize(real_part,imag_part,signal_length);

旧代码和问题：

.dat文件看起来像是带有数字(以空格隔开)的两个直列

我收到有关循环读取数据的错误(strtok-> atof(空指针))

编辑了ert_main.cpp主要功能：

#include /* This ert_main.c example uses printf/fflush */

#include "Rx.h" /* Model's header file */

#include "rtwtypes.h" /* MathWorks types */

#include

#include "mat.h"

#define lengthOFSignal 5000

#define SizeOfLine 35

int_T main(int_T argc, const char *argv[])

{

/* Unused arguments */

(void)(argc);

(void)(argv);

int i=0;

char bFileName[] = "QPSK_SISO_802_11_packet_awgn_fr_shft.dat";

char chr[SizeOfLine*lengthOFSignal];

char *token;

real_T real_part[lengthOFSignal];

real_T image_part[lengthOFSignal];

int signal_length=0;

std::ifstream iFile(bFileName, std::ios::binary);

iFile.getline(chr,100);

for(int i=0; i

if (chr== NULL) break;

token= strtok(chr," ");

real_part[i]=atof(token); // real part.---problem occurs here!!!!

token= strtok(NULL," ");

image_part[i]=atof(token);// imaginary part.

iFile.getline(chr,100);

signal_length++;

}

iFile.close();

/* Initialize model */

Rx_initialize(real_part,image_part,signal_length);

/* Attach rt_OneStep to a timer or interrupt service routine with

* period 40.0 seconds (the model's base sample time) here. The

* call syntax for rt_OneStep is

*

* rt_OneStep();

*/

printf("Warning: The simulation will run forever. "

"Generated ERT main won't simulate model step behavior. "

"To change this behavior select the 'MAT-file logging' option.\n");

fflush((NULL));

while (rtmGetErrorStatus(Rx_M) == (NULL)) {

/* Perform other application tasks here */

rt_OneStep();

if(Rx_Y.EVM!=0) break;

}

/* Disable rt_OneStep() here */

/* Terminate model */

Rx_terminate();

return 0;
