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
