• Understand the difference Built-In and

User-Defined MATLAB Functions

• Write User Defined Functions

• Describe Global and Local Variables

• When to use SUBfunctions as opposed to

NESTED-Functions

• Import Data from an External Data-File

– As generated, for example, by an Electronic

Data-Acquisition System

Private Functions

• Private functions reside in subdirectories with the

special name private, and they are visible only

to fcns in the parent directory

• Assume the directory wmays is on the MATLAB

search path. A subdirectory of wmays called

private may contain functions that only the

functions in wmays can call.

• Because private functions are invisible outside the

parent directory wmays, they can use the same

names as functions in other directories.
