Chapter 4 Functions and variables

4.1 Functions

The following list of functions is available. Each of these functions is placed in individual .m files (See brief description in Table 3.1). Additionally, the AfDaq.m file includes different callback functions associated with different sub-components of the GUI. These are self-explanatory with a brief explanation given in the function file itself.
