<p> Set a property (field) value of an FIS structure and return the
updated FIS.
</p>
<div class="ms-5">
<p> There are three forms of setfis:
</p>
<table>
<thead><tr><th width="20%">Number of Arguments</th><th width="70%">Action Taken</th></tr></thead>
<tr><td width="20%">3</td><td width="70%">Set a property of the FIS structure. The properties that may
be set are: name, type, andmethod, ormethod, impmethod,
addmethod, defuzzmethod, and version.</td></tr>
<tr><td width="20%">5</td><td width="70%">Set a property of an input or output variable of the FIS
structure. The properties that may be set are: name and range.</td></tr>
<tr><td width="20%">7</td><td width="70%">Set a property of a membership function. The properties that
may be set are: name, type, and params.</td></tr>
</table>
<br>
<p> The types/values of the arguments are expected to be:
</p>
<table>
<thead><tr><th width="20%">Argument</th><th width="70%">Expected Type or Value</th></tr></thead>
<tr><td width="20%"><var>fis</var></td><td width="70%">an FIS structure</td></tr>

’ormethod’, ’impmethod’, ’addmethod’,
’defuzzmethod’, and ’version’ (case-insensitive)</td></tr>

<tr><td width="20%"><var>in_or_out</var></td><td width="70%">either ’input’ or ’output’ (case-insensitive)</td></tr>
