So, the ‘switch-case’ command is very useful in Matlab®. Conclusion For ‘switch-case’ Command In Matlab® We used direct numbers after ‘cases’ which represent the cases of written mathematical expression on ‘switch’.įor example, we typed ’45’ for angle degree at the command window, and the result is the first area of the trigonometrical zone.

We divided the angle ‘a’ with 90 to obtain the zone. If you look at the use of the switch, fix() is used to round the angle that is taken from the user. In this example executed in Matlab®, we take a degree of angle from the user with input() command, But there is a difference in the use of switch-else use in this example. > a = input('Enter the degree of angle:') ĭisp('Angle is in the first area of trigonometric zone.')ĭisp('Angle is in the second area of trigonometric zone.')ĭisp('Angle is in the third area of trigonometric zone.')ĭisp('Angle is in the fourth area of trigonometric zone.')Īngle is in the first area of trigonometric zone. This is another example to understand the use of the ‘switch-case-otherwise’ command in Matlab®.

So, we are typing the values of ‘a’ inside curly brackets of ‘cases’ commands.Īt the end of ‘cases’, we put a command called ‘otherwise’ inside which we can put a code if the user enters a value for ‘a’ which is not inside any of the cases. For example, for the first case, if the user enters 0, 1, or 2, the program will display the letter grade ‘E’. Beneath the ‘switch’ command, we typed all the cases.

Inside the ‘switch()’ command, we put the variable ‘a’ inside parentheses. With the input() command,we are taking the examination mark from users.Īfter that, we used switch-case to corresponding letter grade to the user. There is a code that includes the use of ‘switch-case’ which is executed in the Matlab® command window.

How To Use ‘switch-case’ In Matlab®? > a = input('Enter the mark that you took from exam(0-10):') ĭisp('You have entered an invalid value.')Įnter the mark that you took from exam(0-10):5 Take a look at the examples below about the use of the ‘switch-case’ command and its syntax in Matlab®. In these cases, the use of a ‘switch-case’ statement can be very useful. For a situation that must be coded in Matlab®, there can be various kinds of cases that needed to have different statements in Matlab® code. Thank you.‘switch-case-otherwise’ is a very useful command in Matlab® to create conditional programs. This should show you why using a switch case statement can be cleaner than its equivalent in an if-then-else statement. And we can see that works also, that either alpha or bravo would work just fine there. And then something specific if it's Charlie. Now, maybe we're interested in doing one thing if it's alpha or bravo. And then we're going to switch through that railroad switch yard based on the different cases. Let's take a look here with strings where we can just say, my string is equal to alpha. One of the other advantages of switch case in where it's most often actually used is with strings. If we come here and put our value as 8 and run it again, we can see that it just goes through and says something else. That's how the switch case works.Īnd if we run it here, we can see that it indeed did find the correct value. And if none of those were correct, then we're just going to say otherwise and do something else. Otherwise, we're going to try case two, case three. If the case is 1, that is if val equals 1, display 1. And so we're going to be switching based on the variable val. Basically, what we're doing is saying, I want to switch through these cases as if it was a switch yard at a train depot or something like that. Notice there's just a lot less characters on screen when we do it this way. How would this look if it were done as a switch? I think this is more clean and easy to understand doing it this way.

Notice in this if/else statement, what we have is someone is creating a val equal to 3 variable, and then checking with a bunch of if/elses to find out what the value is. Today in MATLAB Basics, we're going to discuss the use of switch case statements as a cleaner, more maintainable way of doing something like this, that you often see done with else/if statements.
