getTunableValues

Obtain values of tunable parameters from fuzzy inference system

Syntax

paramvals = getTunableValues(fis,paramset)

Description

paramvals = getTunableValues(fis,paramset) returns tunable parameter values of the fuzzy inference system fis. To specify the parameter values to return, use paramset.

Examples

Obtain Values of Tunable Parameters from FIS

Create a fuzzy inference system, and define the tunable parameter settings of inputs, outputs, and rules.

fis = mamfis('NumInputs',2,'NumOutputs',1);
[in,out,rule] = getTunableSettings(fis);

Obtain tunable parameter values of the inputs, outputs, and rules of the fuzzy inference system.

paramVals = getTunableValues(fis,[in;out;rule]);

Input Arguments

fis — Fuzzy inference system

mamfis object | sugfis object | mamfistype2 object | sugfistype2 object | fistree object

Fuzzy inference system, specified as one of the following:

• mamfis object — Mamdani fuzzy inference system

• sugfis object — Sugeno fuzzy inference system

• mamfistype2 object — Type-2 Mamdani fuzzy inference system

• sugfistype2 object — Type-2 Sugeno fuzzy inference system

• fistree object — Tree of interconnected fuzzy inference systems

Fuzzy inference system, specified as a mamfis, sugfis, mamfistype2, sugfistype2, or fistree object.

paramset — Tunable parameter settings

array

Tunable parameter settings, specified as an array of input, output, and rule parameter settings in the input FIS. To obtain these parameter settings, use the getTunableSettings function with the input fis.

paramset can be the input, output, or rule parameter settings, or any combination of these settings.

Output Arguments

paramvals — Tunable parameter values

array

Tunable parameter values, returned as an array. The order of the values in paramvals matches the order of the parameters in paramset.

You can modify these parameter values, and then set them in your FIS using setTunableValues.
