calculates the eigenvectors for orthogonal projection with Dynamic Orthogonal Projection
[ploads,ev_pcent] = dop(xi,yi,xo,yo,kernel_thresh,pca_thresh)
calibration dataset; a matrix (n x q) and a vector (n x 1) or Div structures
disturbed spectra; a matrix (no x q) or a Div structure
the reference values associated to the disturbed spectra; a vector (n0 x 1) or a Div structure
thresholds to determine the size of the kernel and the number of eigenvectors respectively (by default=0.01)
eigenvectors of the detrimental space of DOP
ploads.d is a matrix of dimensions (q x nfacteurs)
eigenvalues standardized such that their sum=1
