How can I compute eigenvectors?
I am a Computer Engineering student. And, on my project I must do PCA
training. So, I have computed eigenvalues via QR algorithm. But, I
don't know how can I compute corresponding eigenvectors via QR. In some
papers I read that, products of Qk is eigenvectors matrix. Is it true?
Please help me.
