something wierd with sinc function
显示 更早的评论
while using sinc(x) function there is a difference between sinc(x) and sin(x)/x also when i manually calculate its equal to
sinc(1.5)= -0.2 (negative value) sin(1.5)/1.5 = 0.6 (positive value)
why?

Sounds like you're using a pi-normalized sinc
>> sin(1.5*pi)/(1.5*pi)
ans =
-0.2122
It's a normalization often used so that the roots of the sinc() will be at the integers.
