# MATLAB - The Nested if Statements

It is always legal in MATLAB to nest if-else statements which means you can use one if or elseif statement inside another if or elseif statement(s).

## Syntax

The syntax for a nested if statement is as follows −

if <expression 1>
% Executes when the boolean expression 1 is true
if <expression 2>
% Executes when the boolean expression 2 is true
end
end

You can nest elseif...else in the similar way as you have nested if statement.

## Example

Create a script file and type the following code in it −

a = 100;
b = 200;
% check the boolean condition
if( a == 100 )
% if condition is true then check the following
if( b == 200 )
% if condition is true then print the following
fprintf('Value of a is 100 and b is 200\n' );
end
end
fprintf('Exact value of a is : %d\n', a );
fprintf('Exact value of b is : %d\n', b );

When you run the file, it displays −

Value of a is 100 and b is 200
Exact value of a is : 100
Exact value of b is : 200
