# BSc II Math A: Chapter 03 Matrices

__BSc Mathematics Chapter number 03 “Matrices”__
This
chapter has great worth is both pure and applied mathematics.

In
many branches of business, biological and social science, it is necessary to
express and use a set of numbers arranged in a rectangular array.

**In this quiz, we have discussed some important topics of “Matrices”.**

**1)**Types of matrices.

a)
Row matrices

b)
Column matrices

c)
diagonal matrices

d)
identity matrices

e)
equal matrices

f)
scalar matrices

g)
zero matrices

**2)**Algebra of matrices.

a)
equality of matrices

b)
zero matrix

c)
addition of matrices

d)
Inverse of matrices

e)
Multiplicative inverse of matrices and additive inverse of matrices.

**3)**Multiplication of two matrices A and B is possible only If number of column in A is equal to the number of rows in B.

The
commutative law for multiplication of matrices does not hold.

**4)**Transpose of a matrix

**5)**Periodic matrix, nilpotent matrix, involutory matrix.

**6)**We have discussed symmetric matrix and skew symmetric matrix.

**7)**Hermitian matrix and skew Hermitian matrix.

**8)**Partitioning of matrices.

**9)**Inverse of a matrix

Let
A be a square matrix of order n. A matrix B of order n is said to be the
inverse of A if AB= BA = I

**10)**Singular matrix and non singular matrix.

**11)**Elementary row and column operation:

a)
Interchange of any two rows or Column of matrix

b)
Multiplication of a row or column of A Matrix by any non zero real or complex
number.

c)
Addition of a scalar multiple of one row or column of A matrix to another row.

**12)**Rank of a matrix.

Number
of non zero rows after echelon operation.
