9 Non-adaptive, Visualization and Help Functions

This chapter documents the functions used to generate plots, manage the iteration progress window, and provide other functionalities that are used by the supported applications. Table 9.1 summarizes those functions and gives a short description and a pointer to the reference page of each function. Some of the help functions, such as ipwin() and guifb() are meant to be used internally by other functions and therefore not documented here.

Table 9.1: Visualization and help functions.

Function Name	Reference	Short Description
init_ ipwin	9.1	Initializes iteration progress GUI window.
ipwin		Builds the iteration progress GUI window.
getStop		Returns the condition of the stop button in the IPWIN.
guifb		Handles the GUI feedback functions of the IPWIN.
mcmixr	9.2	Calculates the response of N speakers at M microphones.
osfilter	9.3	fast FIR filter using overlap-save.
plot_ ale	9.4	Generates plots for the Adaptive Line Enhancer problems.
plot_ anvc	9.5	Generates plots for Active Noise and Vibration Control.
plot_ beam	9.6	Generates plots for beam forming problems.
plot_ echo	9.7	Generates plots for echo canceling applications.
plot_ invmodel	9.8	Generates plots for inverse modeling problems.
plot_ model	9.9	Generates plots for modeling problems.
plot_ predict	9.10	Generates plots for linear prediction problems.
sovfilt	9.11	Second Order Volterra filter.
update_ ipwin	9.12	Updates the iteration progress GUI window.

Each of the help functions is documented in a separate section including the following information related to the function:

• Purpose: Short description of the function.
• Syntax: Shows the function calling syntax. If the function has optional parameters, this section will have two calling syntaxes. One with only the required formal parameters and one with all the formal parameters. You can leave out an optional parameter when you call the function or use [] to use its default value.
• Description: Detailed description of the function usage with explanation of its input and output parameters.
• Example: A short example showing typical use of the function.
• Remarks: Gives more remarks specific to the usage of the function.
• See Also: Lists other functions that are related to this function.
