Performing conditional steps using if statements

…One of the capabilities built into any…modern programming language, is conditional execution of code.…What that means, is that a programming environment such as…Octave, can check to see whether a particular condition is true.…If it is, then it can execute or not execute code as you desire.…In this movie, I will show you one way…to do that conditional programming in Octave using if statements.…I will provide a basis overview in PowerPoint and then I'll switch…over to Notepad to create a script that we can run in Octave.…

The basic if statement has three components.…The first, is the if statement, which has a condition in parentheses.…And I'll show you how to do that, once I get into the demonstration part.…Then, in the middle, you have the statements…that are executed if the condition is true.…And finally, the endif statement, which indicates the end of the if block.…Note, that the endif statement is all one term.…There's no space between the d and the i.…

If you want, you can have Octave execute code if…the condition is true and if the condition is not true.…
