By putting a decimal point and a number in the format command, you are telling the program to print only two decimal places. The following ways to "print" information are also available in Matlab, but are "frowned" upon, except for rapid debugging of a program. Any time you print information, you should make sure it is of interest to the user of the program every time the code is run.
For example a function that compute pi should never use fprintf. Instead, such a function should return the value of pi for use by other parts of the program. In CS, we will not use script files , which are m-files without function headers more details on this later. A program function's name should be the same as the m-file name in which it is stored. A function's name should be descriptive of what the function does or follow CS requirements, e.
Include the parentheses after the function's name to distinguish it from a variable name even though the parentheses are not required. The MATLAB help function will display the program comment header block comment lines immediately following the function header There are several ways to run a program: Type its name at the command line prompt the program must be saved in a file that is stored in a folder in your MATLAB search path. The command interpreter will catch and, as best as it can, identify syntax errors when you attempt to run your program.
If an error message looks like a "hyper-link", you can click on the error message to "jump" directly to the location in your program where the error was recognized. Copy the program header template into your new m-file. Enter a function name on the first line e. Save your file as a m-file e. Update the comment header block with the appropriate information. Add code and comments below the comment header block. Re-save your m-file.
Run and test your program.
