vanderMonde

vanderMonde,hyperSpec-method

vandermonde generates van der Monde matrices, the hyperSpec method generates a hyperSpec object
containing the van der Monde matrix of the wavelengths of a hyperSpec object.

Comfortable ways to work with hyperspectral data sets.
I.e. spatially or time-resolved spectra, or spectra with any other kind
of information associated with each of the spectra. The spectra can be data
as obtained in XRF, UV/VIS, Fluorescence, AES, NIR, IR, Raman, NMR, MS,
etc. More generally, any data that is recorded over a discretized variable,
e.g. absorbance = f(wavelength), stored as a vector of absorbance values
for discrete wavelengths is suitable.
