Special Types of Matrices Introduction: This chapter studies special types of matrices. They are: idempotent matrices, nilpotent matrices, involutary matrices, projection matrices, tridiagonal matrices, circulant matrices, Vander-monde matrices, Hadamard matrices, permutation matrices, doubly stochastic matrices, and nonnegative matrices Here is a matrix of size 2 3 (2 by 3), because it has 2 rows and 3 columns: 10 2 015 The matrix consists of 6 entries or elements. In general, an m n matrix has m rows and n columns and has mn entries. Example Here is a matrix of size 2 2 (an order 2 square matrix): 4 1 3 2 The boldfaced entries lie on the main diagonal of the matrix

Hence both are the zero matrix. A = 1 2 (A+AT)+ 1 2 (A−AT). Examples. A = J 0 −1 10 o is skew-symmetric. Let B =} 12 −14] BT =} 1 −1 24] B −BT =} 03 −30] B +BT =} 21 18]. Then B = 1 2 (B −BT)+ 1 2 (B +BT). An important observation about matrix multiplication is related to ideas from vector spaces tary matrix obtained from the identity by the same transformation. This is illustrated below for each of the three elementary row transformations. 1.5.2 Elementary Matrices and Elementary Row Opera-tions Interchanging Two Rows (R i) \$(R j) Proposition 99 To interchange rows i and j of matrix A, that is to simulate (R i) \$( 4.2. MATRIX NORMS 217 Before giving examples of matrix norms, we need to re-view some basic deﬁnitions about matrices. Given any matrix A =(a ij) ∈ M m,n(C), the conjugate A of A is the matrix such that A ij = a ij, 1 ≤ i ≤ m, 1 ≤ j ≤ n. The transpose of A is the n×m matrix A￿ such that A￿ ij = a ji, 1 ≤ i ≤ m, 1 ≤ j ≤ n

• Matrix multiplication is where a matrix is multiplied by another matrix. - this is covered in a later leaﬂet. To multiply a matrix by a scalar (that is, a single number), we simply multiply each element in the matrix by this number. Using the matrices above we have the following: 5B = 5× 5 5× −2 5× −1 5×3 5× 1 5×0
• Types of Matrices 1) Row Matrix. A row matrix has only one row but any number of columns. A matrix is said to be a row matrix if it has... 2) Column Matrix. A column matrix has only one column but any number of rows. A matrix is said to be a column matrix if... 3) Square Matrix. A square matrix has.
• TYPES OF MATRIX ROW MATRIX : having only row elements. COLUMN MATRIX: having only column elements. SQUARE MATRIX : whose order is (nXn). RECTANGULAR MATRIX : whose column elements are not equal to row element. DIAGNAL MATRIX : A square matrix is called a diagonal matrix if all its diagonal elements are non zero. SCALAR MATRIX: a diagonal matrix in which all diagonal elements are equal to a scalar quantity. UNIT OR IDENTITY MATRIX: a square matrix in which all the diagonal elements are equal.
• Types of Matrices 1. Row Matrix A matrix having only one row and any number of columns is called a row matrix. 2. Column Matrix A matrix having only one column and any number of rows is called column matrix. 3. Rectangular Matrix A matrix of order m x n, such that m ≠ n, is called rectangular matrix. 4

Important Formulas for Matrices If A, B are square matrices of order n, and I n is a corresponding unit matrix, then (a) A(adj.A) = | A | I n = (adj A) A (b) | adj A | = | A |n-1 (Thus A (adj A) is always a scalar matrix) (c) adj (adj.A) = | A | n-2 A (e) ∣ a d j (a d j
• Multiplying any matrix M by a square matrix S on either side results in a matrix of the same size as M, provided that the sizes of the matrices are such that the multiplication is allowed. If S is the identity matrix I, then the result is the original matrix M: 88 Chapter 7: Introduction to Matrices Equation7.5: 2×2matrix multiplication.
• There are different common types of matrices like row matrix, column matrix, null matrix, rectangular matrix, square matrix, diagonal matrix, unit matrix, upper triangular matrix, lower triangular matrix etc

polymer matrix composite provides strength and stiffness that are lacking in the matrix. The com-posite is designed so that the mechanical loads to which the structure is subjected in service are supported by the reinforcement. The function of the relatively weak matrix is to bond the fibers together and to transfer loads between them, A quadratic forms and their matrix notation Ifq=a 1 x 2 +a 2 y 2 +a 3 z 2 +a 4 xy+a 5 xz+a 6 yz then q is called a quadratic form (in variables x,y,z). There i s a q value (a scalar) at every point. (To a physicist, q is probably the energy of a system with ingredients x,y,z. Reducing a matrix to reduced row echelon form or rref is a means of solving the equations. In this process, three types of row operations my be performed. 1) Each element of a row may be multiplied or divided by a number, 2) Two rows may exchange positions, 3) a multiple of one row may b The reason it is called the identity matrix is because AI= IA= A. 2.2.3 Square, Symmetric, and ranspTose Matrices A square matrix is a matrix whose number of rows is the same as its number of columns. orF example, the identity matrix is always square. If a square matrix has the property that a i;j = a j;i for all its elements, then we call it a. A matrix is a collection of numbers ordered by rows and columns. It is customary to enclose the elements of a matrix in parentheses, brackets, or braces. For example, the following is a matrix: X = 5 8 2 − 1 0 7 . This matrix has two rows and three columns, so it is referred to as a 2 by 3 matrix. Th

• 3. There exists an additive identity matrix, the m n matrix whose entries are all 00s. If we denote this matrix by 0, then it has the following property: A+0 = 0+A = A. 4. Each matrix has an additive inverse. The additive inverse of A is A. It satis-es: A+( A) = A+A = 0, where 0 is the zero matrix here. Proof
• Some simple hand calculations show that for each matrix Gauss Decomposition: Notice that in the -term factorization the first and third factors are triangular matrices with 's along the diagonal, the first (ower) the third (pper), while the middle factor is a (iagonal) matrix. This is an example of the so-called -decomposition of a matrix

Types of Matrices Row Matrix. If a matrix has just one row, we will call it a row matrix. Number of columns doesn't matter in a row... Column Matrix. Column matrix is like a row matrix but with some changes. The condition of the column matrix is that it... Rectangular Matrix. A rectangular matrix is. There are several types of matrices, but the most commonly used are: Rows Matrix Columns Matrix Rectangular Matrix Square Matrix Diagonal Matrix Scalar Matrix Identity Matrix Triangular Matrix Null o School of Mathematics | School of Mathematic The purpose of this paper is to define different types of matrices in fuzzy soft set theory. We have introduced here some new operations on these matrices and discussed here all these definitions and operations by appropriate examples. Moreover a new efficient solution procedure has been developed to solve fuzzy soft set based real life decision making problems which may contain more than on

38 Partitioned Matrices, Rank, and Eigenvalues Chap. 2 as a product of block matrices of the forms (I X 0 I), (I 0 Y I). In other words, we want to get a matrix in the above form by per-forming type III operations on the block matrix in (2.3). Add the ﬁrst row of (2.3) times A−1 to the second row to get (A B I A−1 +A−1B) Types of Matrix - There are some special matrices which are outlined below: Column Matrix - A matrix with a single column and any rows is called a column matrix. For a column matrix M, the order is m x 1. Row Matrix - A matrix with a single row and any number of columns is called a row matrix. For a row matrix M, the order is 1 x n 2. Quadratic Forms De nition 3. A quadratic form is a function Qon Rngiven by Q(x) = xTAx where Ais an n n symmetric matrix, called the matrix of the quadratic form. Example 6. The function x 7!kxkis a quadratic form given by setting A= I. Quadratic forms appear in di erential geometry, physics, economics, and statistics. Example 7. Let A= 5.
