WebA matrix is of order (or dimension) m by n (also denoted as (m x n)). A matrix that has a single column is called a column vector. A matrix that has a single row is called a row vector. TRANSPOSE The transposeof a matrix or vector is formed by interchanging the rows and the columns. WebFor example, the 1, 2 entry of the matrix A above is 2, the 2, 1 entry is 0, and the 2, 3 entry is $\pi$.Very often we write $A=(x_{ij})$ to mean that A is a matrix whose i, j entry is $x_{ij}$.. If two matrices A and B are the same size (that is, they are both m n for the same m and n) then we add and subtract them by adding and subtracting each entry separately:
