It is designed to illustrate the similarity between the If Action Subsystem block and the Enabled Subsystem block. A pulse generator is connected to an If block, which compares the input to zero. If the input is positive, as specified by the if condition, then the If Action Subsystem Abs is activated, which outputs the absolute value of the sine wave input signal.

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. The commands inside the else are executed only if the test condition on the if statement is false. If the test condition on the if statement is true, the commands inside the if are executed, and the commands inside the else are skipped. Thus, only the commands inside the if or the commands inside the else will be executed, never both.
