7 - Control Structures - 1 11 - Control Structures In all the code we’ve looked at thus far, the computer has followed commands one by one. A control structure is a command which allows the computer to make a decision and act accordingly. Control structures fall in two categories: branches and loops . Conditional control structures We begin with branches, also known as conditional control structures . A branch tests to see if a condition is true. If it is, then it does something. If not, it skips to the next part of the program. MATLAB branch commands have the following form: if condition expression(s) elseif condition expression(s) else expression(s) end There can be any number of elseif’s . For example, imagine we were purchasing box cars for a railroad company and the price of each car depends upon how many we purchase. If we buy 3 or less, the price is $22K each. If we buy between 4 and 10, we pay $20K each. And if we buy more than 10, the price is $19K each. Here is a function that will return the total cost of railroad cars based on the number that we want to buy: %carprice %calculates the total price railroad cars %based on the number being bought %E77 reader %07-01 D# function [cost] = carprice (number) if number > 10
