Octave Fuzzy Logic Toolkit: setfis

### Function Reference: `setfis`

Function File: fis = setfis (fis, property, property_value)
Function File: fis = setfis (fis, in_or_out, var_index, var_property, var_property_value)
Function File: fis = setfis (fis, in_or_out, var_index, mf, mf_index, mf_property, mf_property_value)

Set a property (field) value of an FIS structure and return the updated FIS.

There are three forms of setfis:

Number of Arguments | Action Taken
--- | ---
3 | Set a property of the FIS structure. The properties that may be set are: name, type, andmethod, ormethod, impmethod, addmethod, defuzzmethod, and version.
5 | Set a property of an input or output variable of the FIS structure. The properties that may be set are: name and range.
7 | Set a property of a membership function. The properties that may be set are: name, type, and params.

The types/values of the arguments are expected to be:

Argument | Expected Type or Value
--- | ---
fis | an FIS structure
property | a string; one of ’name’, ’type’, ’andmethod’, ’ormethod’, ’impmethod’, ’addmethod’, ’defuzzmethod’, and ’version’ (case-insensitive)
property_value | a number (if property is ’version’); a string (otherwise)
in_or_out | either ’input’ or ’output’ (case-insensitive)
var_index | a valid integer index of an input or output FIS variable
var_property | a string; either ’name’ or ’range’
var_property_value | a string (if var_property is ’name’) or a vector range (if var_property is ’range’)
mf | the string ’mf’
mf_index | a valid integer index of a membership function
mf_property | a string; one of ’name’, ’type’, or ’params’
mf_property_value | a string (if mf_property is ’name’ or ’type’); an array (if mf_property is ’params’)

Note that all of the strings representing properties above are case insensitive.
