**how to find the covariance matix & eigen value MATLAB**

How do we find out covariance of a 3 D matrix? knowing the fact that covariance is always measured between two dimensions... Indeed, there is no ready function in MATLAB for generating random numbers from the general t-distribution and I could not find with quick googling any readily available function. Assuming that by covariance, you mean either variance (scalar case) or covariance matrix here is …

**linear algebra Covariance matrix of two matrices- how to**

yes,I am getting 12 x 12 covariance matrix, but m loosing the data in this case because the matrix M here is that of an image and later in the program i have to reconstruct it into 256 x 256 to get the image... I am trying to find the posterior covariance matrix from a gaussian process using MatLab. The GP model is formed as follows:

**How to Compute Variance & Covariance in Excel YouTube**

I am trying to find the posterior covariance matrix from a gaussian process using MatLab. The GP model is formed as follows: how to get to tsim sha tsui from airport I am trying to find the posterior covariance matrix from a gaussian process using MatLab. The GP model is formed as follows:

**covariance of a matrix which is not a square matrix**

I want to check the covariance matrix of a colored noise if it is correct. I started to see how to find the covariance matrix of a white noise first. how to find the independent variable in an article I was just started applying Principal Component analysis on 3D face data set. I arrange the data in a cell. I try to find the covariance using the below code:

## How To Find Covariance Matlab

Hi all, I have a question about Mahalanobis distance using the matlab function. In fact I have this Mlahnobis function {e' inv{C} e } wehre e ? N (0, C) is a vector 1*n size and C its covariance matrix (n*4) * (n*4), because each element of e has a 4*4 covariance matrix in the diagonal of C.

- I am guessing that you don't need covariance of two matrices, but a covariance matrix for all pairs of columns. But I might be wrong. You'd need the first one, in case your random variable is the whole matrix. But if you consider each element as your random variable, then you can calculate the mean, and variance for each column of covariance for each pair of columns.
- 25/06/2013 · You just use the cov() function. But, if you're trying to find the covariance of one vector, that is, one vector containing samples of one variable, matlab is going to give you the variance.
- then we will calculate the covariance matrix (32 X 32) so we get 32 eigenvalues the question is: does these eigenvalues express the 32 images? or there is no …
- I'm not sure how to back out the weights of a portfolio given the covariance matrix of the assets and variance of the portfolio using matlab. I have the following inputs:
