![]() ![]() To improve the appearance of this function the user can add \n to the command, which will cause everything following the symbol to appear in the next line. Note that the variable x will be assigned the user input for the remainder of the code unless another function reassigns its value. The user would type their response where the yellow box is next to the prompt. An example of the input command is to the right. The user is then able to respond to the prompt by entering in their input directly after the prompt in the command window. With the input command, the user can have MATLAB provide a prompt in the command window. The input function, typed input, operates as a way for the user to assign a value to a variable. Additionally, it is important to understand that this command is not the best way to prompt users to input data or other information into the code, as the input command is best suited for that function. ![]() Note that the message being displayed cannot contain apostrophes, as the code will stop reading the message there. Everything else in the quotations will be displayed in the command window by the program. To use the display command, type disp followed by a set of parentheses with single quotations inside of them. ![]() The display command appears in the following format in MATLAB. This can include instructions about the code’s function that appear when the user runs the code, greetings for the user, error messages, or conclusions determined by the code. The display command is an excellent way to give instructions or other information in the command window for the user of the code. The display command (typed “disp”) allows the user to instruct the program to display a message in the command window. This chapter will introduce several functions which will be prevalent within ME 160 and will drastically expand the number of applications for MATLAB. By piecing together commands with instructions a “map” will be created which enables the code to complete the user’s desired operation. Often represented as puzzle pieces in introductory programming guides, commands enable the code to interact with the user, finish tasks in response to user inputs, or serve as a road map within the code. Commands will serve as tools that complete defined tasks within a MATLAB code. ![]()
