Hello, ive got this code in Wolfram Mathematica,

Multiply all the eigenvectors with the matrix centered, then look for the relationship between the variance and the eigenvalues:

Use all the eigenvectors to compare each of the matrices that were obtained.

Hope someone can help. Program works, its only to do as says there.

If need the .mlx file, can provide email or something so i can send it in order to answer the question easier. Please, its urgent.
