MATLAB PROGRAMMING. SCRIPTS and FUNCTIONS

Scripts are the simplest kind of program fil because they have no input or output arguments. They are useful for automating series of MATLAB commands, such as computations that you have to perform repeatedly from the command line or series of commands you have to reference.Scripts and functions allow you to reuse sequences of commands by storing them in program files Scripts are the simplest type of program, since they store commands exactly as you would type them at the command line. However, functions are more flexibland more easily extensible. instead of manually updating the script each time, you can make your programmore flexibl by converting it to a function. Replace the statements that assign values to band h with a function declaration statement. The declaration includes the function keyword, the names of input and output arguments, and the name of the function. Functions have their own workspace, separate from the base workspace.MATLAB scripts, including live scripts, can contain code to defin functions. These functions are called local functions. Local functions are useful if you want to reuse codewithin a script. By adding local functions, you can avoid creating and managing separate function files They are also useful for experimenting with functions, which can be added, modified and deleted easily as needed.Local functions are only visible within the fil where they are defined both to the script code and other local functions within the file They are not visible to functions in otherfiles and cannot be called from the command line. They are equivalent to subroutines inother programming languages, and are sometimes called subfunctions. MATLAB live scripts and live functions are interactive documents that combine MATLAB code with formatted text, equations, and images in a single environment called the LiveEditor. In addition, live scripts store and display output along side the code that creates it.Live scripts are program file that contain your code, output, and formatted text togetherin a single interactive environment called the Live Editor. In live scripts, you can write your code and view the generated output and graphics along with the code that producedit. Add formatted text, images, hyperlinks, and equations to create an interactivenarrative that you can share with others.To diagnose problems in your live scripts or functions, debug your code in the Live Editor. A simple way to determine where a problem occurs in your live script or function is toshow output. To show the output for a line, remove the semi-colon from the end of thatline. The Live Editor displays each output with the line of code that creates it, making iteasy to determine where a problem occurs.
