where can I find the "interval type 2 fuzzy logic system" IT2FLS toolboxs.
i need to download it & start using it in my matlab the same way i use the Fuzzy logic toolbox which comes with matlab
Thanx in advance ...

How to download mamdai type 2 fuzzy logic .When I am downloading IT2FLS from matlab it gives sugeno type 2 fuzzy logic not mamdani type 2 fuzzy logic.

Hello
i am looking for the type-é logic toolbox with Mamdani inference, i work on Matlab2020a
help me download the toolbox (IT2-FLS Mamdani), show me steps i have to follow them
thank you so much

Click on the green Code button. Choose Download Zip. Extract the zip into a convenient directory that is not part of the MATLAB distribution. Then use the MATLAB pathtool command. Navigate to the directory you just extracted into, into the type-2-fuzzy-logic-systems-matlab-toolbox-main directory and add that to your MATLAB path. Then at the MATLAB command prompt, command
fuzzyt2

Hello sir,
I followed all your instructions but I can't open the fuzzy logic type-2 interface, that's what it shows me in the command window :
>> fuzzyt2
t2fis =
struct with fields:
name: 'Test'
type: 'sugeno'
andMethod: 'prod'
orMethod: 'probor'
defuzzMethod: 'wtaver'
impMethod: 'prod'
aggMethod: 'sum'
typeRedMethod: 'KM'
input: [1×2 struct]
output: [1×1 struct]
rule: [1×4 struct]
y =
0.1576
, I don't know what to do?
I would be very grateful thank you very much sir
Walter Roberson
2021 年 6 月 28 日
Yes, the code did what the authors intended. It added the fuzzyt2 routines to your MATLAB path, and then it ran an example to show that it was working.
The toolbox has no graphic interface.
There are examples provided to demonstrate its use.

2021 年 6 月 28 日
Ah! Okay !
I thought it is similar to the fuzzy logic toolbox type1 !, so it's good! I just have to follow the examples to build my program to get program (.fis), then I can run it under Simulink as type 1.
with mamfistype2 : it's for mamdani's inference.
I want to thank you very very very much very much sir
a great respect to you

We're proud to introduce the research community with an open source Matlab/Simulink toolbox for Interval Type-2 Fuzzy Logic Systems (IT2-FLS) by Ahmet Taskin and Tufan Kumbasar. The current version of the IT2-FLS toolbox allows intuitive implementation of IT2-FLSs where it is capable to cover all the phases of its design. We would like to encourage the research community to contribute to the development of the IT2-FLS toolbox through suggestions, comments or contributions.
More detailed information about the toolbox and its download link can be found in:

Visit the above page. There is a download link that will allow you to download a .rar . Extract the rar into a convenient directory that is not part of the MATLAB distribution. Then use the MATLAB pathtool command. Navigate to the directory you just extracted into, down below the IT2FLSv1.0 directory to the IT2-FLS_Toolbox-v1.0 directory and add that to your MATLAB path. Then at the MATLAB command prompt, command

The toolbox only allows for three(3) membership functions per input variable. I would like to know if there is any update to the toolbox?
Tufan Kumbasar
2016 年 2 月 15 日
I would like to inform you that we have found the problem and have updated the toolbox. In revised version of the toolbox, you should be able to edit number and parameters of the input & output MFs.
You can find the updated version from the following link:
Thanks for your feedback,

The toolbox appears to run in R2016a for me. However, for non-MS Windows systems, you need to change several statements in fuzzyt2 to use fullfile instead of concatenating strings together.
addpath(fullfile(hpath,'IT2FLSs_Toolbox_Funcs'))
addpath(fullfile(hpath,'TR_Methods_Funcs'))
addpath(fullfile(hpath,'Simulink_Lib'))
addpath(fullfile(hpath,'Images'))

hi Tufan Kumbasar,
I run the example "runEdgeDetectionExample.m" with other image size 2400x1935 and I got this error.
Index in position 2 exceeds array bounds (must not exceed 1935).
Error in runEdgeDetectionExample (line 58)
Ieval(ii,jj) = evalt2([(Ix(ii,jj));(Iy(ii,jj));]',t2fis,TRMethod);
Could you help me?

I am pointing out that type 2 fuzzy is now part of MATLAB, so you do not need to use the third-party toolbox.

Hello everyone;
For those who are looking for the GUI (graphical unit interface) of type-2 sugeno (TKS) inference! well, go to the usual github link: https://github.com/ahmettaskin/type-2-fuzzy-logic-systems-matlab-toolbox for the shown last version of this toolbox doesn't show the GUI but the older vesion does (stiil work) just click on #main then choose #tags and dowload the v1.0 INSTEAD of v1.1 and the graphical unit inference of type-2 fuzzy sets will open and work ^^.
Have a good day guys!

error:Unable to convert from matlab.graphics.GraphicsPlaceholder to logical.
Walter Roberson
2019 年 4 月 25 日
I suspect there is a place where an graphics handle initialized to 0 is implicitly compared to 0, something like
if Lines(2)
as an abbreviation for
if Lines(2) ~= 0
which used to be a valid way to test whether a graphics handle had been stored into the location.
In current MATLAB, you would in this circumstance use isvalid(), such as
if isvalid(Lines(2))

I wrote to the corresponding author of Interval Type2 Fuzzy Logic Toolbox (IT2FLS), Engineering Letters volume 15 issue 1; unfortunately I received no reply.
However, there is another toolbox called MFLS described in Toolbox for Interval Type-2 Fuzzy Logic Systems. I was able to reach the corresponding author, who cleared the code for public use. Visit his page and go down to almost the bottom, to item 15, and click on the link there that says "[Software]" in order to obtain the toolbox. I am advised that the code was written for SciLab originally and so might need some tuning to work with MATLAB.

I have not worked with Fuzzy Logic myself, and I have no idea what zslices method is. All I did was searches to find the code for other people to use, because the question had been asked a number of times.
