Plot an ellipse The code will plot any ellipse where you specify the major and minor axis distances, optional translation by \(x, y\) units, and an optional rotation. Expected result:kevindunn on 22 August 2011

Principal components analysis (PCA) using a sequential method The singular value decomposition is usually presented as the way to calculate the PCA decomposition of a data matrix. The NIPALS algorithm is a very computationally tractable way of calculating ...kevindunn on 08 August 2011 (revision 3)
