MATLAB Relational Operators

Matlab Operators

Relational operators can also handle scalar and non-scalar data. Array relational operators perform element-by-element comparison between two arrays and return a logically sized array of the same size, with elements set to logical1(true), the relationship is true, the element is set to logical 0(false). Not.

The following table shows the relational operators-

Serial NumberOperators and Descriptions
1

<

Less

2

<=

Less than or equal

3

>

Greater

4

>=

Greater than or equal

5

==

Equal

6

~=

Not equal

Online Example

Create a script file and enter the following code-

a =　100;
b =　200;
if (a >= b)
max = a
else
max = b
end
When you run the file, it will produce the following result-
max =　　200

In addition to the above relational operators, MATLAB also provides the following commands for the same purpose/Function-

Serial NumberFunction Description
1

eq(a, b)

Test if a is equal to b

2

ge(a, b)

Test if a is greater than or equal to b

3

gt(a, b)

Test if a is greater than b

4

le(a, b)

Test if a is less than or equal to b

5

lt(a, b)

Test if a is less than b

6

ne(a, b)

Test if a is not equal to b

7

isequal

Test if the array is equal

8

isequaln

Test if the array is equal, treating NaN values as equal

Online Example

Create a script file and enter the following code-

%Comparison of two values
a =　100;
b =　200;
if (ge(a, b))
max = a
else
max = b
end
%Comparison of two different values
a =　340;
b =　520;
if (le(a, b))
　　　disp('a is less than or equal to b')
else
　　　disp('a is greater than b')
end
When running the file, it will produce the following result-
max =　　200
a is less than or equal to b
