setTunableValues

Specify tunable parameter values of a fuzzy inference system

Since R2019a

Syntax

fisOut = setTunableValues(fisIn,paramset,paramvals)

___ = setTunableValues(___,'IgnoreInvalidParameters',ignoreInvalid)

Description

fisOut = setTunableValues(fisIn,paramset,paramvals) sets the tunable parameter values of fuzzy inference system fisIn and returns the resulting fuzzy system in fisOut. To specify the parameters to set, use paramset. Specify the new parameter values using paramvals.

___ = setTunableValues(___,'IgnoreInvalidParameters',ignoreInvalid) sets a flag for ignoring invalid parameters values.

Examples

Specify Tunable Parameter Values of a FIS

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

fis = mamfis('Name','fis1','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]);

Redefine some of the values and update the tunable parameter values of the FIS.

paramVals(1:3) = [0 0 1];
fis = setTunableValues(fis,[in;out;rule],paramVals);

Input Arguments

fisIn — Fuzzy inference system

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

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.

paramvals — Tunable parameter values

array

Tunable parameter values, specified as an array. The order of the values in paramvals matches the order of the parameters in paramset. To obtain the array of parameter values for a FIS, use getTunableValues.

ignoreInvalid — Flag to ignore invalid parameters

array

Flag to ignore invalid parameters, specified as either true or false. If true, invalid paramvals are replaced with the existing parameter values of a fuzzy system.

Output Arguments

fisOut — Modified fuzzy inference system

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

Modified fuzzy inference system, returned as a mamfis, sugfis, mamfistype2, or sugfistype2, or fistree object.

fisOut is the same as fisIn except that the parameters specified by paramset have the values specified by paramvals.
