Sample matrix inversion

Sample matrix inversion (or direct matrix inversion) is an algorithm that estimates weights of an array (adaptive filter) by replacing the correlation matrix with its estimate. Using -dimensional samples , an unbiased estimate of , the correlation matrix of the array signals, may be obtained by means of a simple averaging scheme: where is the conjugate transpose. The expression of the theoretically optimal weights requires the inverse of , and the inverse of the estimates matrix is then used for finding estimated optimal weights. (Wikipedia).

Transpose of matrices

In this very easy and short tutorial I explain the concept of the transpose of matrices, where we exchange rows for columns. The matrices have some properties that you should be aware of. These include how to the the transpose of the product of matrices and in the transpose of the invers

Matrix addition

How do we add matrices. A matrix is an abstract object that exists in its own right, and in this sense, it is similar to a natural number, or a complex number, or even a polynomial. Each element in a matrix has an address by way of the row in which it is and the column in which it is. Y
