MATLAB nested if-else

If statements can be nested, but each if statement requires the end keyword.

Syntax:

  if expression  Statements  if expression  Statements  else  Statements  end  elseif expression  Statements  if expression  Statements  end  else   Statements  end  

Example1

  % nested if-elseif-else program  num = randi(100,1);  a = input(‘enter a number greater than 1 and less than 10 : ‘)  disp([‘the random number is : ‘, num2str(num)])  if a <= 1 || a >= 10      disp(‘please try again & enter the number in between 1 & 10’)  elseif rem(num,a) == 0          if rem(num,2) == 0              if rem(a,2) == 0                  disp(‘you entered an even number, and the random number is also even’)              else                  disp(‘random number is even and divisible by the entered number’)              end          else              disp(‘random number is odd but divisible by the entered number’)          end  elseif num < a      disp(‘random number is smaller than the  entered number, please try again ‘)  else      disp(‘random number is not divisible by the entered number’)  end  

Output:

enter a number greater than 1 and less than 10: 9  a = 9  the random number is: 14  the random number is not divisible by the entered number

Example 2:

  % create a random number, max. 100, and a scalar  a = randi(100,1)  % use quorem function(takes symbolic variables as arguments) to get quotient & remainder  [Q,R] = quorem(sym(a),sym(2))  if R == 0            if rem(Q,2) == 0           disp(‘random number-even’)          disp(‘result-even’)               else          disp(‘random number-even’)          disp(‘result-odd’)      end  else      if rem(Q,2) == 0           disp(‘random number-odd’)          disp(‘result-even’)               else          disp(‘random number-odd’)          disp(‘result-odd’)      end  end
