wl.eval {hyperSpec}

Evaluate function on wavelengths of hyperSpec object

Description

This is useful for generating certain types of baseline "reference spectra".

Usage

wl.eval(x, ..., normalize.wl = I)

Arguments

x

hyperSpec object

...

hyperSpec method: expressions to be evaluated

normalize.wl

function to transorm the wavelengths before evaluating the polynomial (or other function). Use normalize01 to map the wavelength range to the interval [0, 1].

Value

hyperSpec object containing one spectrum for each expression
