The elseif and else blocks are optional. The statements execute only if previous expressions in the if An if block can include multiple elseif blocks.

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. If the input to the If block is not positive, as specified by the else condition, then the If Action Subsystem Saturation between The outputs of the two subsystems are never active at the same time and are merged into one signal with a Merge block. The scope shows the sine wave input, the triggering pulse input, and the merged and biased output. When the pulse is on, the output is the absolute value of the sine wave. When the pulse is off, the output is the clipped version of the sine wave. Choose a web site to get translated content where available and see local events and offers.

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.

Loops use a for or while keyword, and conditional statements use if or switch. Additional keywords provide finer control over the program flow. To determine which block of code to execute at run time, use if or switch conditional statements. To repeatedly execute a block of code, use for and while loops.
