![]() This forms part of the old polynomial API. The number of columns of the input x is 4, so the result is a 4 by 4 covariance matrix.Mathematical functions with automatic domain In the above example, the output shows the covariance matrix of a 3 by 4 matrix as input to it. To calculate the covariance of a 3 by 4 matrix: ![]() Please find the below examples that show the use of covariance in Matlab:īelow are the examples of covariance in Matlab: Example #1 If the inputs are in the form of two by two matrix, then the output argument is in the form of 2 by 2 covariance matrix representing the variance between two variables. ![]() If there is a single matrix input, then the output has a size similar to the number of variables present in the input argument and the variances of the columns are represented in the diagonal.
