Representation of Relations
- Relation as a Matrix: Let P = [a1,a2,a3,…….am] and Q = [b1,b2,b3……bn] are finite sets, containing m and n number of elements respectively.
- Relation as a Directed Graph: There is another way of picturing a relation R when R is a relation from a finite set to itself.

How do you tell if a relation is transitive from a matrix?
Transitive matrix: A matrix is said to be transitive if and only if the element of the matrix a is related to b and b is related to c, then a is also related to c. That is, if (a,b) and (b,c) exist, then (a,c) also exist otherwise matrix is non-transitive.
What are various types of representation of matrix?
Types of Matrices: Summary
| Type of Matrix | Representation Details |
|---|---|
| Square Matrix | A=[aij]m×n where m=n |
| Diagonal Matrix | A=[aij]n×n where aij=0 for i≠j |
| Scalar Matrix | A=[aij]n×n where aij={0i≠jki=j} Here k is a constant. |
| Identity or Unit Matrix | A=[aij]n×n where aij={0i≠j1i=j} |
How do I create a relation matrix in Excel?

Relations can be displayed in multiple ways:
- Table: the x-values and y-values are listed in separate columns; each row represents an ordered pair.
- Mapping: shows the domain and range as separate clusters of values.
- Graph: each ordered pair is plotted as a point and can be used to show the relationships between values.
What is matrix data analysis?

What is matrix defined?
Matrices are defined as a rectangular array of numbers or functions. Since it is a rectangular array, it is 2-dimensional. Basically, a two-dimensional matrix consists of the number of rows (m) and a number of columns (n). The order of matrix is equal to m x n (also pronounced as ‘m by n’). Order of Matrix = Number of Rows x Number of Columns
