  • A matrix of rank m×n is a rectangular system consisting of m×n arranged elements, distributed in lines and columns, and surrounded by parentheses. We symbolize this set of elements with a capital letter:

    Example:

    We call the elements of the matrix for which the line number is equal to the column number as diagonal elements.

    If the matrix is square, then the diagonal elements form what is called the diagonal of the matrix, which is called...

    Sometimes the main diameter of this matrix

    We say that matrix B is diagonal if it is a square and all of its elements are zero except for the diagonal elements.
