What does sinc do in Matlab?

Viewed as a function of time, or space, the sinc function is the inverse Fourier transform of the rectangular pulse in frequency centered at zero, with width 2 π and unit height: sinc x = 1 2 π ∫ - π π e j ω x d ω = sin π x π x , x ≠ 0 , 1 , x = 0 .

How do you plot a sinc function?

The sinc function is the continuous inverse Fourier transform of the rectangular pulse of width and height 1. for all other elements of x . To plot the sinc function for a linearly spaced vector with values ranging from -5 to 5, use the following commands: x = linspace(-5,5); y = sinc(x); plot(x,y)

How do you create a sine function in Matlab?

Y = sin( X ) returns the sine of the elements of X . The sin function operates element-wise on arrays. The function accepts both real and complex inputs.

What is sinc integration?

The integral of a function is the value of its Fourier transform at zero, so sinc integrates to π. [ 1] By Plancherel's theorem, the integral of sinc²(x) is the integral of its Fourier transform squared, which equals π. [There are several conventions for defining the Fourier transform.
