A flexible method is introduced to model the structure of a covariance matrix C and study the dependence of the covariances on explanatory variables by observing that for any real symmetric matrix A, ...

In this video we will learn about integral power of a matrix, matrix polynomial, symmetric matrix and skew-symmetric matrix. In this video we will learn about integral power of a matrix, matrix ...
