How to import 256*3 size input table into fuzzy?

Error using evalfis:

Specify a valid type-1 FIS structure.

[Walter Roberson]

Is the table you want to import a set of FIS rules, such as if you only triangle FIS?

Or is it a table of data to evaluate against a fis that has already been constructed?

I am not able to figure out the error here.

I have been struggling with this from months. I sincerely appreciate any sort of help/guidance on this

@华纳公司注册网址hn6660.com, Why not showing how you designed the FIS, and you inserted it into evalfis()?

Table of data given as input and expected output should be the best data among all the data?

Facing error in evaluation. How should get the best data from the input to be displayed?

Kindly help me out.

Code:

fismat = readfis('Fuzzy2'); % fuzzy get loaded
output =evalfis(S1,fismat); %Facing error

Input: is in struct form

Error:

Error using fuzzy.internal.utility.readFISAsStructure>localReadFIS

Too many input arguments.

Error in fuzzy.internal.utility.readFISAsStructure (line 29)

[out,errorMsg] = localReadFIS(varargin{:});

Error in fuzzy.internal.utility.readfis (line 27)

[varargout{1:nargout}] = fuzzy.internal.utility.readFISAsStructure(varargin{:});

Error in readfis (line 27)

[varargout{1:nargout}] = fuzzy.internal.utility.readfis(varargin{:});

Error in evalfis (line 71)

inRange = readfis(fis,'inRange');

Error in main (line 69)

o=evalfis(HVS,fismat);

Hi @Aberna P

From your code, we can analyze something.

fismat = readfis('Fuzzy2');     % fuzzy get loaded
output = evalfis(S1, fismat);   % facing error

Before R2018b, to evaluate a fuzzy inference system, fismat, using evalfis(), the first input argument is the input variable values.

https://www.mathworks.com/help/fuzzy/evalfis.html#mw_bb57a9c0-133c-4f69-afb5-b54292ff6147

Since R2018b, the input argument order has changed to

output = evalfis(fismat, S1);

Since you used the former syntax, you must be using R2018a or earlier version.

Is Fuzzy2.fis a Type-2 fuzzy system? If it is a Type-2 fuzzy system, and the Interval Type-2 FIS structure was introduced in R2019b, naturally the error message will tell you to specify a valid Type-1 FIS structure.
