addvar

(Removed) Add variable to fuzzy inference system

addvarhas been removed. Use addInput or addOutput instead. For more information, see Version History.

Syntax

outfis = addvar(infis,varType,varName,varRange)

Description

outfis = addvar(infis,varType,varName,varRange) adds an input or output variable to the fuzzy system infis with the specified name and range.

Indices are applied to variables in the order in which they are added. For example, the first input variable added to a system is input variable number one for that system. Input and output variables are numbered independently.

Examples

Add Variable to Fuzzy Inference System

Create a new FIS.

fis = newfis('tipper');

Add a new input variable.

fis = addvar(fis,'input','service',[0 10]);

getfis(fis,'input',1)

ans = struct with fields:
      Name: 'service'
    NumMFs: 0
     range: [0 10]

Input Arguments

infis — Fuzzy system

mamfis object | sugfis object

Fuzzy system, specified as a FIS object.

varType — Variable type

'input' | 'output'

Variable type, specified as either 'input' or 'output'.

varName — Variable name

string | character vector

Variable name, specified as a string or character vector.

varRange — Variable range

two-element vector

Variable range, specified as a two-element vector, where the first element is the minimum value and the second element is the maximum value for the variable.

Updated fuzzy system, returned as a FIS object.

Version History

Introduced before R2006a

R2024b: Removed

addvar has been removed. To add input or output variables to a fuzzy system, use addInput or addOutput, respectively.

This table shows some typical usages of addvar and how to update your code to use addInput or addOutput instead.

If your code has this form:	Use this code instead:
fis = addvar(fis,'input',... 'service',[0 10])	fis = addInput(fis,[0 10],... 'Name',"service")
fis = addvar(fis,'output',... 'tip',[0 30])	fis = addOutput(fis,[0 30],... 'Name',"tip")

R2019b: Warns

addvar issues a warning that it will be removed in a future release.

R2018b: To be removed

addvar runs without warning, but Code Analyzer indicates that addvar will be removed in a future release.
