Unable to replicate example from matlab webiste for Report generator

Good afternoon everybody,

I get a weird error from Matlab when I try to execute the code which is avilable at this web-page https://it.mathworks.com/help/rptgen/ug/create-a-report-generator.html

If I try to execute line by line I'm stopped at the first "append" istance of the script.

What is the reason? Thank you for your help.

import mlreportgen.report.*
import mlreportgen.dom.*
rpt = Report('magic','html');
tp = TitlePage;
tp.Title = 'Magic Squares';
tp.Subtitle = 'Columns, Rows, Diagonals: All Equal Sums';
tp.Author = 'Albrecht Durer';
append(rpt,tp);

Error using append (line 49)
Input must be a string array, character vector, or cell array of character vectors.

Works for me in R2020b. What version of MATLAB are you using?

Same error here R2019b.

says Introduced in R2020b

Hmm... might be time for an upgrade...

This example was first introduced in R2018a. It was updated for R2020b to use the append function (previously used add instead).

If you are using R2018a-2020a, try using the release-specific example rather than the one you linked to. For R2020a, the release-specific example can be found at the following url:

Ahhh..ok that's the point.. I'm currently using the R2019a and as you suggested, if I replace append with add it works.

Thank you very much Cris!
