To plot the Fourier transform of a 1000 point sine wave in Matlab, you can use the fft
function. Here's an example code that generates a sine wave signal, applies the Fourier transform, and plots the magnitude and phase of the Fourier transform:

In this example, we generate a 1000-point sine wave signal with a frequency of 10 Hz. We then apply the FFT using the fft
function, and compute the magnitude and phase of the FFT using the abs
and angle
functions, respectively. Finally, we plot the magnitude and phase spectra using the plot
function, and label the axes and titles appropriately.
