Often we want to execute a command only if a certain test condition is satisfied. We use if statements to do this. If you want to execute certain commands only when a certain test condition is met, use a simple if statement of the form:. In myfile. In the example above, the test condition on the if statement was satisfied it was true since the value stored in x was indeed great than 4. Because the test condition was true, the statements inside the if were executed, and the final values of x and y after the if statement were different than the initial values. An if, else statement will allow you to execute certain commands if a test condition is true and execute other commands if the test condition is false.

Conditional statements are something that is very basic and important for every programmer. There will be some situations where a program or a particular block has to be executed only when a specific condition is True. These conditional statements will be very handy and fruitful in such situations. These conditional statements work as same as in other languages. However, syntax varies from language to language. An if-end statement is the simplest decision-making statement. It decides whether a particular block of code has to be executed or not, based on the given boolean condition. Only when the given condition is true, it executes the statements inside the block otherwise not. Example 2: You can also chain if-else-end statements with more than one condition.

But to get a false output you would need all of its terms to be false , and that will never happen. There is at least one value above the limit. But when I checked the result, it did not do the 'and' statement. Alternatively, when you want to test for equality against a set of known values, use a switch statement. The space creates a nested if statement that requires its own end keyword. Answers Support MathWorks. I want to detect the exact index point at which the values start changing from the 0.
