Computes Numeric Fourier Integrals

Computes Fourier integrals of functions of one and two variables using the Fast Fourier transform. The Fourier transforms must be evaluated on a regular grid for fast evaluation.

Guillermo Basulto-Elias

This is a package in R to numerically calculate Fourier-type integrals of univariate and bivariate functions with compact support and simultaneously evaluated at several points. If the evaluation grid is equally spaced, a Fast Fourier Transform method is used to speed up computations.

See detailed documentation on the vignette (type browseVignettes("fourierin") and then click "HTML").


Version 0.2.2

  • Suggested package 'microbenchmark' has been replaced by 'rbenchmark'.

  • Parameters are more intuitive
  • Vignette hes been improved

Version 0.1.2

Patch: microbenchmark is now used only conditionally.

Version 0.1.1

This first version of the package includes univariate and bivariate Fourier-type integrals.
