txt转bin c与matlab

因为c代码需要读取.bin文件，尝试用matlab转一下格式

a = textread('rrcreconfig78.txt','%s');
a=hex2dec(a);

fid = fopen('rrcreconfig78.bin', 'w');
fwrite(fid,a,'uint8');
fclose(fid);

fid = fopen('rrcreconfig78.bin', 'r');
input1 =fread(fid,'uint8');
size(input1)
fclose(fid);

尝试的时候一直用的char，所以导致数据有误，具体原因等matlab修炼有成再深究

#include "stdio.h"
#include 
#include 

int main()
{
    char buf[1000] = {0};
    int pdu_length = 0,first = 0;
    FILE *ff = fopen("rrcreconfig78.txt", "r");
    //fseek(ff, 0, SEEK_END);
    //pdu_length = ftell(ff);
    //printf("pdu len %dn", pdu_length);
    //fseek(ff, 0, SEEK_SET);
    do
    {
        if (!first)
        {
            first = 1;
        }
        else
        {
            pdu_length++;
        }
    }while (fscanf(ff, "%x", (int *)&buf[pdu_length]) != EOF);

    fclose(ff);
        
    ff = fopen("rrcreconfig78.bin", "w+");
    fwrite((void *)buf,1,pdu_length,ff);
    fclose(ff);
    return 0;
}

后续增加读取指定文件的功能
