Bonnet’s recursion formula for Legendre polynomials is(adsbygoogle = window.adsbygoogle || []).push({});

P(n,x)=1 for n=0

P(n,x)=x for n=1 and

P(n,x)= (2n-1)/n*x*P(n-1,x)-(n-1)/n*P(n-2,x)

I tried to write recursive function in C to calculate the value of polynomial for a given n and x

But this doesn't give the correct result. What's wrong with the function??Code (Text):float legpol(int n, float x)

{

if(n==0)

return 1;

else if(n==1)

return x;

else

return(2*n-1)/n*x*legpol(n-1,x)-(n-1)/n*legpol(n-2,x);

}

Thanks in advance
