Programmatically generating Report Generator

hey, i want to Export the results(Images and Text) of my mfile into a pdf-Report. I did it for the first Test and it works fine. But when i use a Loop to generate many Reports and save them in a Folder it didn't work.The code i could write can be use only for one Report or Image. it should look like this in the folder:

• report1
• report2

if true
import mlreportgen.report.*
import mlreportgen.dom.*
rpt = Report('Test','pdf');
tp=TitlePage;
tp.Title = 'Fehlerbericht des BNSE-Tests';
tp.Author = 'Idriss Moffo';
add(rpt,tp);
ch1 = Chapter();
ch1.Title = 'Störszenario: Menuesprung';
sec1 = Section;
sec1.Title = 'Last Image';
imageObj1 = Image(which('A.png'));
imageObj1.Height = '3in';
imageObj1.Width = '5in';
add(sec1,imageObj1);
add(ch1,sec1);
add(rpt,ch1);
close(rpt);
rptview(rpt.OutputPath);
end

Hi,

From the code it seems that the output report name is always kept the same. So if you generate multiple reports in a loop while keeping the output report name same, the generated report will be overridden in every loop iteration and hence you will see only one PDF report at the end. To fix this, just update the report name in every loop iteration using a counter. Below is a sample code:

% Specify a counter variable before the loop
counter = uint8(0);

% Start of the loop
for a = 1:10
    % Your code in the loop

      if true
          % Your code ....

          % Increament the counter and use it to create report name
          counter = counter + 1;
          rpt_name = strcat('report', int2str(counter));

          % Create the report using this report name
          rpt = Report(rpt_name,'pdf');

          % Rest of the code ....
      end

end % End of the loop

Thank you Rahul. It solves my Problem. Is there any method how i can store all the generated reports to a Folder? actually they are automatically saved in the Folder containing the M-File.

thank you

Sure, you can provide the full path for the output file instead of just providing the file name as specified in the documentation of the OutputPath property of Report class.

You can also use MATLAB fullfile to build the full file name.

Hey Rahul, thanks for your replies. I solved the Problem using fullfile. Now i will try to implement the Report function that it always check if the Name already exists, such as avoiding overriding when i restart the code. for example: today: report1, report2, report3 tomorrow:...., report4, report5...

Thank you

See if you can use use persistent counter variable for this use case.

Another alternative is to save the counter variable to a MAT-file using the save command at the end of the day, and then load the updated value from this MAT-file using the load command next day.
