In this video, we will get to learn about the Inverse of a Matrix and its Applications in solving the simultaneous equation. a) A is a matrix formed by all the coefficients in the system b) X is a ...

Some years ago the author defined a pseudo inverse of a singular matrix and used it in representing a solution of normal equations and for obtaining variances and covariances of estimates in the ...

In this paper, we give the results for the Drazin inverse of P + Q, then derive a representation for the Drazin inverse of a block matrix M=( A B C D ) under some ...

Random Matrix Theory (RMT) has emerged as an indispensable framework for understanding the statistical properties of matrices whose entries are determined by probabilistic processes. Initially ...
