Detailed Description

Spectral Angle Kernel.

Performs an inverse multiquadric kernel evaluation that suits spectral data.

It is of kind:

$ frac{1}{\sqrt{ c_0 + \cos\textrm{SAM(x, y)} }} $ where $ \textrm{SAM(x, y)} $ is Spectral Angle Measure: $ \textrm{SAM}(x, y) = \cos^{-1}\left( \frac{x \cdot y}{\|x\| \|y\|} \right) $.

The only parameter $ c_0 $ is to be fixed by the

SetValue

interface with keyword Coef (def 2.0).
