[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
