How can I effectively use switch cases in MATLAB for decision-making in my code?

Switch cases in MATLAB provide a clear and efficient way to handle multiple conditions in your code. They are particularly useful when you need to execute different blocks of code based on the value of a variable. Here’s a detailed example:

x = input('Enter a number: ');

switch x
    case 1
        disp('You entered one.');
    case 2
        disp('You entered two.');
    case 3
        disp('You entered three.');
    otherwise
        disp('Number not recognized.');
end

In this example, the input function prompts the user to enter a number. The switch statement then evaluates the value of x and executes the corresponding case block. If x is 1, it displays 'You entered one.' If x is 2, it displays 'You entered two.', and so on. If none of the specified cases match, the otherwise block is executed, displaying 'Number not recognized.'

Switch cases are an excellent way to manage multiple conditions, making your code more organized and easier to read. They are especially useful in scenarios where you have a finite number of possible values for a variable and need to perform different actions based on those values.
