Thread: Convolution in C

"f[1]*\a[1]"? Really?

Also your if statement has a 1 in it, which it shouldn't. (Which, incidentally, also erroneously appears in your f[] thing.)

Code:

#include<stdio.h>
#include<math.h>
#include<conio.h>
#include<stdlib.h>
double o[6]={0,0,0,0,0,0};

int main()
{
     int i;
     int x,y;
     double f[7]={3.2,3.4,5.3,4.5,6.5,0,0};
     double a[7]={1.2,3.2,0,0,0,0,0};
     
     o[1]=(f[1]*\a[1]);  <--- syntax error     

printf("%f",o[1]);
     
      /*for(x=0;x<6;x++)     <--- all this is commented out
      {
           o[x]=0;
           
                  for(y=0;y<1;y++)
                  {
                                   if(x-y+1>0)
                                   {
                                   o[x]=o[x]+(a[y]*f[x-y+1]);
                                   }
                                   }
                                   }
     for(i=0;i<6;i++)
     {
                         printf("%f\n",o[i]);
                         }*/                         system("pause");
     return(0);
}
                             
      Why is this not working? i checked, n i found that the multiplication is not taking place properly,
