UTL_NLApackage, we can call routines to perform PCA on vectors and matrices represented as
VARRAYs. How ever, vectors and matrices are stored in
VARRAYs with a maximum size of one million entries. Given this restriction,
UTL_NLAvectors can be up to one million entries but matrices need to be of size RxC <= 1,000,000.
That's why I have developed my own functions to perform PCA. It is much easier to use and can handle unlimited number of records. Data and operations always stay in the database.
