i am new to s function,,,how to create s function from existing matlab or c code

#include<math.h>
#include<conio.h>
#include<stdio.h>
  
main()
{
int root,n,i,m,seq2[100];
float x,y,seq,seq1[100],sum=0,avg,pi=3.142;
clrscr();
root=36;
m=16;
i=1;
for(n=1;n<=m;n++)
{

 x=((root*n*(n+1)*pi)/m);
/*  printf("exp=%f",exp(-x)); */
 y=-x;
 printf("x=%f\t  y=%f \t \n ",x,y);
 seq=exp(y); /*this line is not working */
 printf(" \n  seq=%f",seq);
 /* seq=exp(-(root*n*(n+1)*PI)/m);  not getting correct output here exp() is not working
 printf(" \n seq=%f",seq); */
 sum=sum+seq;
 seq1[i]=seq;
 i=i+1;
 }

 avg=sum/m;
 for(i=1;i<=m;i++)
 {
    if(seq1[i]>=avg)
    {
       seq2[i]=1;
      }
      else
      {seq2[i]=0;
      }
    printf("\n binary=%d",seq2[i]);
 }

 getch();
 }
