9 ASPT Naming conventions

To manage the large and continuously increasing number of routines included in ASPT, and to protect naming conflicts with other packages, the Matlab implementation of ASPT uses several naming conventions. Each routine name consists of two parts. The first part is a prefix indicating the category to which the routine belongs. For example, all initialization routines start with the init_ prefix. The second part of the routine name is a description of the algorithm or function performed by the routine. For example, the init_lms() routine initializes the variables and structures for the Least Mean Squares (LMS) adaptive filter. The following prefixes are currently in use.

• init_ : used for initialization routines.
• aspt : used for adaptive filters routines.
• plot_ : used for plotting routines.

Several non-adaptive routines that do not contribute to the set of adaptive algorithms but perform complementary functions required by the toolbox are also included in the ASPT distribution. Examples of those functions are osfilter() and sovfilt() that implement an overlap-save frequency domain fixed filter, and a second order Volterra fixed filter, respectively. To keep the names of those routines descriptive, the naming conventions rules mentioned above do not apply to those helper routines.
