%description
Implementation of two-dimensional (2D) correlation analysis based on the
Fourier-transformation approach described by Isao Noda (I. Noda (1993)
<DOI:10.1366/0003702934067694>). Additionally there are two plot functions
for the resulting correlation matrix: The first one creates colored 2D
plots, while the second one generates 3D plots.
