The .zip file contains the following .m files:
For more information on the syntax of the files, enter help
at the MATLAB prompt.
- 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
- 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.
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
