Matrices

Matrix of ones

In mathematics, a matrix of ones or all-ones matrix is a matrix where every entry is equal to one. Examples of standard notation are given below: Some sources call the all-ones matrix the unit matrix, but that term may also refer to the identity matrix, a different matrix. A vector of ones or all-ones vector is matrix of ones having row or column form; it should not be confused with unit vectors. (Wikipedia).

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
