Nested Switch in MATLAB
Last Updated :
21 Nov, 2022
Switch statements in MATLAB allow having multiple cases as conditionals. It is an implementation of the simple if-elif-else-end cycle but, better. In this article, we will see how nested switch statements work in MATLAB with the help of example.
Syntax:
switch choice_1
case <1>
switch choice_2
case <B>
statements
.
end %end of inner switch
.
end %end of outer switch
Now we see the below example printing the switch whether it is inner or outer.
Example 1:
Matlab
choice1 = input( "Enter choice between 1 and 3" );
choice2 = input( "Enter second choice between 1 and 2" );
switch choice1
case 1
fprintf( "first and second choices are in outer loop" )
case 2
switch choice2
case 1
fprintf( "Second choice is in inner loop" )
case 2
fprintf( "Inner choice is in inner loop" )
end
case 3
fprintf( "This choice is in outer loop" )
end
|
Output:
Now we will use the nested switch for the situation where if the input number is 0, it prints “It is zero!” else if it is not 0, it will ask for new choice whether you want to print the number or its square root.
Example 2:
Matlab
choice1 = input( "Enter choice between 0 or any other number for next menu" );
switch choice1
case 0
fprintf( "It is a zero!" )
otherwise
choice2 = input( "Enter -1 for same and 1 for square root" );
switch choice2
case -1
disp(choice1)
case 1
disp(sqrt(choice1))
end
end
