This program do this: Copy the seccond column from one file like this, its file name is peso.txt

I'll take out the other columns to use only one column for use in matlab (this looks like a homework jeje) RemoveDate.c

#include {stdio.h} //change "{" for "less than <"
#include {conio.h} //change "}" for "greater than >"
void main ()
{
 FILE *balanza ;
 FILE *matlab ; 
 char c ;
 int i = 0, s = -1 ;
 printf("\tCentro de Ciencias Aplicadas al Desarrollo Tecnologico CCADET\n\n") ;
 printf("\n\t\tBALANZA'S FILE MUST BE NAMED: peso.txt\n\n") ;
 printf("\t\tTHE OUTPUT FILE IS matlab.m\n\n") ;
 system("PAUSE") ;
 balanza = fopen ("g:/peso.txt","r") ; //select the input file dir
 matlab = fopen("g:/matlab.m","w") ;  //select the output file dir
 fprintf(matlab,"b=[") ;
 while (c != EOF)
 {             
           if(c == '\n') 
           {
                i=0;
                s++;
                fprintf(matlab,"\n") ;
           }
           if(c == ' ') 
           {  
                i++;
                if(i==5) 
                {
                         printf("\n\n\t") ;
                }
           }
           c=getc(balanza) ;
           if(i>3&&i<5)
           {
                  fprintf(matlab,"%c",c) ;
                  printf("%c",c) ;
           }
 }
 fprintf(matlab,"\b] ;\n") ;
 fprintf(matlab,"t=[0:1:%d] ;\n",s) ;
 fprintf(matlab,"plot(t,b) ;\n") ;
 fprintf(matlab,"xlabel('Tiempo [s]')\n") ;
 fprintf(matlab,"ylabel('Peso [g]')\n") ;
 fprintf(matlab,"legend('peso de la muestra [g]') ;") ;
 fclose(matlab) ;
 fclose(balanza) ;
 printf("\t\t\tSIZE OF TIME: %d\n\n",s) ;
 printf("\t\tDATE AND TIME HAS BEEN REMOVED FROM *peso.txt*\n\n") ;
 system("PAUSE") ;
}

Open the output file matlab.m and see your graph (press F5)
