how to use buitin functions like fcm in gui?

I am trying to implment a GUI for a project. I have to use the fcm builtin function . How to call this function from the gui from the callback and display back the results and

as well plot the image of the dataset.

A GUI in Matlab is nothing special. You need to have working code first, and then put that into a GUI. If you have trouble with the first step, the second not relevant yet.

If you want advice about how to make a GUI, read this thread.

Your tags sugest that you're planning to use GUIDE. Especially if you're creating a GUI from scratch I would strongly advise you to not use GUIDE. It is slated to be discontinued and it can be complex to create anything that isn't simple.

What should i use then?

[Rik]

I would suggest a programmatic GUI, either function-based or class-based.

Have you read the thread I linked?

[Maddie]

Yes I did. I'm new to all to this just starting to automate my project. So I need something simple .

I need to choose a dataset and upload it to my project, call a custom function and the output- which is a figure, will be displayed in the gui or wherever might be possible.

At least this simple functional.

Well, I and others have given you some hints in that other thread. Where are you getting stuck?

Start with what code you want to run. Then think what inputs that would need, then create a GUI figure that will allow you to collect that input. Then as the last step you can let the output of your code be displayed in your figure as well.

I'm not sure what guidance I could further give you, so you'll have to ask a more specific question.

This is the ui of the project:

classdef app1 < matlab.apps.AppBase

    % Properties that correspond to app components
    properties (Access = public)
        UIFigure               matlab.ui.Figure
        BrowseButton           matlab.ui.control.Button
        ClusterEditFieldLabel  matlab.ui.control.Label
        ClusterField           matlab.ui.control.NumericEditField
        Button                 matlab.ui.control.Button
        UIAxes                 matlab.ui.control.UIAxes
        EditFieldLabel         matlab.ui.control.Label
        EditField              matlab.ui.control.EditField
    end


    properties (Access = private)
        data % Description
        cluster % Description
    end


    % Callbacks that handle component events
    methods (Access = private)

        % Button pushed function: BrowseButton
        function BrowseButtonPushed(app, event)
           [filename, pathname] = uigetfile({'*.txt'},'Please select a file to upload.');
             fullpath = strcat(pathname,filename);
              app.data=load(fullpath);
           
            
        end

        % Button pushed function: Button
        function ButtonPushed(app, event)
            forkmean(app.data,app.cluster);
            
        end

        % Value changed function: ClusterField
        function ClusterFieldValueChanged(app, event)
            value = app.ClusterField.Value;
            app.cluster=value;
        end

        % Value changed function: EditField
        function EditFieldValueChanged(app, event)
            value = app.EditField.Value;
            app.EditField.Value= app.data;
        end
    end

    % Component initialization
    methods (Access = private)

        % Create UIFigure and components
        function createComponents(app)

            % Create UIFigure and hide until all components are created
            app.UIFigure = uifigure('Visible', 'off');
            app.UIFigure.Position = [100 100 640 480];
            app.UIFigure.Name = 'UI Figure';

            % Create BrowseButton
            app.BrowseButton = uibutton(app.UIFigure, 'push');
            app.BrowseButton.ButtonPushedFcn = createCallbackFcn(app, @BrowseButtonPushed, true);
            app.BrowseButton.Position = [501 424 100 22];
            app.BrowseButton.Text = 'Browse';

            % Create ClusterEditFieldLabel
            app.ClusterEditFieldLabel = uilabel(app.UIFigure);
            app.ClusterEditFieldLabel.HorizontalAlignment = 'right';
            app.ClusterEditFieldLabel.VerticalAlignment = 'top';
            app.ClusterEditFieldLabel.Position = [435 362 54 15];
            app.ClusterEditFieldLabel.Text = 'Cluster #';

            % Create ClusterField
            app.ClusterField = uieditfield(app.UIFigure, 'numeric');
            app.ClusterField.ValueChangedFcn = createCallbackFcn(app, @ClusterFieldValueChanged, true);
            app.ClusterField.Position = [504 358 100 22];

            % Create Button
            app.Button = uibutton(app.UIFigure, 'push');
            app.Button.ButtonPushedFcn = createCallbackFcn(app, @ButtonPushed, true);
            app.Button.Position = [502 272 100 22];

            % Create UIAxes
            app.UIAxes = uiaxes(app.UIFigure);
            title(app.UIAxes, 'Title')

            app.UIAxes.GridAlpha = 0.15;
            app.UIAxes.MinorGridAlpha = 0.25;
            app.UIAxes.Position = [26 102 407 350];

            % Create EditFieldLabel

            app.EditFieldLabel.Text = 'Edit Field';

            % Create EditField
            app.EditField = uieditfield(app.UIFigure, 'text');
            app.EditField.ValueChangedFcn = createCallbackFcn(app, @EditFieldValueChanged, true);
            app.EditField.Position = [482 209 100 22];

            % Show the figure after all components are created
            app.UIFigure.Visible = 'on';
        end
    end

    % App creation and deletion
    methods (Access = public)

        % Construct app
        function app = app1

            % Create UIFigure and components
            createComponents(app)

            % Register the app with App Designer
            registerApp(app, app.UIFigure)

            if nargout == 0
                clear app
            end
        end

        % Code that executes before app deletion
        function delete(app)

            % Delete UIFigure when app is deleted
            delete(app.UIFigure)
        end
    end
end 

This is a function that I called form the callback of the ButtonPushed I want to plot this graph generated from this function in the axes.

function forkmean(data,K)

[idx,C] = kmeans(data,K);
figure, 

gscatter(data(:,1),data(:,2),idx);
hold on
for i = 1:5
    scatter(C(i,1),C(i,2) ,96, 'black','filled');
    
end
legend({'Cluster 1', 'Cluster 2', 'Cluster 3', 'Cluster 4', 'Cluster 5'})
xlabel('Annual Income');
ylabel('Spending Scores')
hold off
end

If you want to plot something in a specific axes, you should provide its handle as the parent in your call to scatter, instead of letting the forkmean function create a new figure.
