Orthogonal Projection Approach (OPA)
This function is a curve resolution method which allows to resolve the data matrix into concentration profiles and pure compound spectra. In the case of batch process data, it is possible to follow with this method the evolution of the concentrations of the different compounds and to get the pure spectra of these compounds.
function (C,A) = opa(X)
Inputs:
X : data matrix, the rows contain the spectra
Outputs:
C : concentration profiles
A : pure compound spectra
Subroutines
opa1, opa2, ...etc
