rmmf

(To be removed) Remove membership function from fuzzy inference system

collapse all in page

rmmf will be removed in a future release. Use removeMF instead. For more information, see Compatibility Considerations.

Syntax

fis = rmmf(fis,varType,varIndex,'mf',mfIndex)

Description

fis = rmmf(fis,varType,varIndex,'mf',mfIndex) removes the membership function, mfIndex, of variable type varType, of index varIndex, from the fuzzy inference system associated with the workspace FIS structure, fis:

  • Specify varType as either 'input' or 'output'.

  • varIndex is an integer for the index of the variable. This index represents the order in which the variables are listed.

  • mfIndex is an integer for the index of the membership function. This index represents the order in which the membership functions are listed.

Examples

Create fuzzy inference system.

fis = newfis('mysys');

Add an input variable with a single membership function to the system.

fis = addvar(fis,'input','temperature',[0 100]);
fis = addmf(fis,'input',1,'cold','trimf',[0 30 60]);

View the variable properties.

getfis(fis,'input',1)
ans = struct with fields:
      Name: 'temperature'
    NumMFs: 1
       mf1: 'cold'
     range: [0 100]

Remove the membership function. To do so, remove membership function 1 from input 1.

fis = rmmf(fis,'input',1,'mf',1);

View the variable properties.

getfis(fis,'input',1)
ans = struct with fields:
      Name: 'temperature'
    NumMFs: 0
     range: [0 100]

The variable now has no membership function.
