mvar Purpose Syntax Description Remove variables from <strong>Fuzzy</strong> Inference System fis2 = rmvar(fis,'varType',varIndex) [fis2,errorStr] = rmvar(fis,'varType',varIndex) fis2 = rmvar(fis,'varType',varIndex) removes the variable 'varType', ofindexvarIndex, from the fuzzy inference system associated with the workspace FIS structure, fis: • The string varType must be 'input' or 'output'. • varIndex is an integer for the index of the variable. This index represents the order in which the variables are listed. [fis2,errorStr] = rmvar(fis,'varType',varIndex) returns any error messages to the string, errorStr. This command automatically alters the rule list to keep its size consistent with the current number of variables. You must delete from theFISanyrulethatcontainsavariableyouwanttoremove,before removing it. You cannot remove a fuzzy variable currently in use in therulelist. Examples a = newfis('mysys'); a = addvar(a,'input','temperature',[0 100]); getfis(a) returns Name = mysys Type = mamdani NumInputs = 1 InLabels = temperature NumOutputs = 0 OutLabels = NumRules = 0 AndMethod = min 4-66
mvar OrMethod = max ImpMethod = min AggMethod = max DefuzzMethod = centroid ans = mysys b = rmvar(a,'input',1); getfis(b) returns ans = mysys Name = mysys Type = mamdani NumInputs = 0 InLabels = NumOutputs = 0 OutLabels = NumRules = 0 AndMethod = min OrMethod = max ImpMethod = min AggMethod = max DefuzzMethod = centroid See Also addmf, addrule, addvar, rmmf 4-67
