Web2 The covariance matrix The concept of the covariance matrix is vital to understanding multivariate Gaussian distributions. Recall that for a pair of random variables X and Y, their covariance is defined as Cov[X,Y] = E[(X −E[X])(Y −E[Y])] = E[XY]−E[X]E[Y]. When working with multiple variables, the covariance matrix provides a succinct ... WebSep 27, 2024 · I have a 2D array (n by n) in Matlab. (see an example of the matrix on the image 1). I want to separate specific parts of the matrix (elements '2') with additional layer of zeros (change "boudnary" elelements to zero, see an image 2 for a desired result in the example matrix).
