Title: Fourier Transform Example
Author: Rainer Stock
Institution: University of Stuttgart
Description: The .zip file contains the following .m files:
  • Fourier.m: Compute the Fourier transform with the trapezoidal integration rule. The number of base points can be selected.
  • plotFourier.m: Create a plot comparing the Fourier transform with the exact function.
  • errorFourier.m: Computes the L2-error (approximation with the of the midpoint integration rule) of the fourier transformation for the function f(x) = abs(x) for an increasing number of base points. An error plot in logarithmic scale is generated as output.
For more information on the syntax of the files, enter help at the MATLAB prompt.

These files were created by a student as a partial fulfillment for the requirements of the course "Classical Mathematical Theorems and their Visualization on the Computer", Winter term 2002/2003, Stuttgart University.
