Function M-files
The objective of this chapter is to enable you to:
Write your own function M-files
We have already seen that MATLAB has a number of built-in (compiled) functions, e.g., sin, sqrt, sum. You can verify that they are built-in by attempting to type them. Try type sin for example. MATLAB also has some functions in the form of function M-files, e.g., fzero, why. You can see what’s in them with type, e.g., type why.
Functions are indispensable when it comes to breaking a problem down into manageable logical pieces. Hence, MATLAB enables you to create your own function M-files. A function M-file is similar to a script file in ...
