I'm implementing a FIR filter, which likes to be h[k] = (3/k^2 +
5/k)*sinc(k) + sinc^2(k)/k+(1/k^2+7/(2*k))*cos(pi*k).
I'd like to make the sample index k between -10 and 10. The problem comes
when k is 0 since k is the denominator. How do I solve this problem? Many
thanks in advance!

Best regards,
