my app designer app having anova1 (statistical toolbox) works perfectly while matlab is open, but it doesn't work as a standalone(.exe) application after deployment.

my app designer app which has anova1 (statistical toolbox) works perfectly while matlab itself is open, but it doesn't work as a standalone(.exe) application after deployment. It gives an "error in anova1" line written in the command prompt. Everything in the app is working fine except anova1 tool. (Matlab R2022b). Any help about it? I checked the build-in functions which are not supported to use in app designer but anova1 is not in the list.

            %% Statistical Analysis (ANOVA) & Plot
            % app.StatisticsDropDown.Value is an input (gui) from the user, which
            % data should be selected for anova analysis thorugh drop down
            % menu. That code work in app designer while matlab is open. 
            if strcmpi(app.StatisticsDropDown.Value, 'Option1')
                [~,~,stats] = anova1(MyMatrix1, MyMatrixGroupName1);
                [c,~,~,gnames] = multcompare(stats);
                tbl = array2table(c,"VariableNames", ...
                    ["Group A","Group B","Lower Limit","A-B","Upper Limit","P-value"]);
                tbl.("Group A") = gnames(tbl.("Group A"));
                tbl.("Group B") = gnames(tbl.("Group B"));
                app.UITable_Stat.Data = tbl;
                app.UITable_Stat.ColumnName = tbl.Properties.VariableNames;
                app.UITable_Stat.RowName = tbl.Properties.RowNames;
            elseif strcmpi(app.StatisticsDropDown.Value, 'Option2')
                [~,~,stats] = anova1(MyMatrix2, MyMatrixGroupName2);
                [c,~,~,gnames] = multcompare(stats);
                tbl = array2table(c,"VariableNames", ...
                    ["Group A","Group B","Lower Limit","A-B","Upper Limit","P-value"]);
                tbl.("Group A") = gnames(tbl.("Group A"));
                tbl.("Group B") = gnames(tbl.("Group B"));
                app.UITable_Stat.Data = tbl;
                app.UITable_Stat.ColumnName = tbl.Properties.VariableNames;
                app.UITable_Stat.RowName = tbl.Properties.RowNames;
            end

Which of the anova1 calls is the one that threw the error?

Does this occur on the first call to anova1 or only after one or more calls succeeded? [My suspicion with this question is that something was overwritten with the wrong type of data.]

What are the contents of MyMatrix1, MyMatrixGroupName1, MyMatrix2, and MyMatrixGroupName2 when the error occurs?

What is the full and exact text of the error message? There should be more information than simply "Error in anova1".

All the errors i get is below:

Unrecognized function or variable 'statdisptable'. Error in anova1 (line 287) Error in myApp_app1/PCR (line 745) which is the line right after if statement. Error in myApp_app1/Button_dCtPushed (line 885) Error in appdesigner.internal.service.AppManagementService/executeCallback (line 172) Error in matlab.apps.AppBase>@(source,event)executeCallback(ams,app,callback,requiresEventData,event) (line 62) Error using matlab.ui.control.internal.controller.ComponentController/executeUserCallback Error while evaluating Button PrivateButtonPushedFcn.

The matrix is 6 (sample replicates) x 16 (groups/column) with 1x16 cell array (group names) as in the syntax of anova1.

As I indicated before it works perfectly fine with matlab in the app designer [r2023a and r2022b]. I get statistical(anova) data in the table, figures showing multiple comparison in the app.

statdisptable is toolbox/stats/stats/statdisptable.m . I would not expect MATLAB to have any trouble finding since it is directly (not at all obscurely) called from anova1.

You could experiment with

%#function statdisptable

in your source code to force the function to be compiled in.

Although it is working but just in case, I removed the if condition and dropdown menu option from the code by leaving just anova1 in the end, still getting the same error. Everyhing is executable until that line of code. Anyways, Thank you all! I will keep trying!

Update: I had to copy and paste the source code (.m) files and their associates function files (anova1 + (statdisptable, fpval) with multcompare) from the path (toolbox>stats) into my application folder. Then I compiled/deployed the application main file with those files required for the standalone app to run. Now it does work perfectly fine as it does in matlab.

Tips: if unrecognized function or variable is received, bring the function used in the code into the current folder that the app file in and compile with them together.

[Walter Roberson]

Copying toolbox code into the path can result in code that will not execute, either because MATLAB complains about the license, or because the code relies upon details of the file structure.

Either use the %#function pragma or use the mcc -a option or use the graphic options of the application compiler to list the additional files.
