pcaproj

[P,V,me,l] = pcaproj(D,arg1,arg2)

PCAPROJ Projects data vectors using Principal Component Analysis.

 [P,V,me,l] = pcaproj(D, odim)
 P =          pcaproj(D, V, me)

  Input and output arguments ([]'s are optional)
   D      (matrix) size dlen x dim, the data matrix
          (struct) data or map struct            
   odim   (scalar) how many principal vectors are used
  
   P      (matrix) size dlen x odim, the projections
   V      (matrix) size dim x odim, principal eigenvectors (unit length)
   me     (vector) size 1 x dim, center point of D
   l      (vector) size 1 x odim, the corresponding eigenvalues, 
                   relative to total sum of eigenvalues
