scripts default iconMatrix Decomposition (Scripts) Publisher's description

Matrix decomposition using, e.g

Matrix decomposition using, e.g. the Cholesky decomposition requires the correlation matrix to be positive definite. That is, the eigenvalues must all be positive. In finance, this is rarely the case, and one often observes negative eigenvalues, or zero eigenvalues. These two functions do essentially the same thing. One adjusts only the <= 0 eigenvalues, while the other adjusts those eigenvalues, but then also increases the other non-negative eigenvalues to compensate for the higher 'weight' given to the smaller eigenvalues.

System Requirements:

MATLAB 7.12 (2011a)
Program Release Status: New Release
