WebThe Fourier transform is defined for a vector x with n uniformly sampled points by. y k + 1 = ∑ j = 0 n - 1 ω j k x j + 1. ω = e - 2 π i / n is one of the n complex roots of unity where i is the imaginary unit. For x and y, the indices j and k range from 0 to n - 1. The fft function in MATLAB® uses a fast Fourier transform algorithm to ... WebUses: Description: The period character separates the integral and fractional parts of a number, such as 3.1415. MATLAB operators that contain a period always work element-wise. The period character also enables you to access the fields in a structure, as well as the properties and methods of an object.
