how can I insert hyperlink (urls) and center alignment of text in a msgbox.
Or is there any alternative solutions?
Problem: I'm working on a matlab app designer app. I'm at the final stage where I need to create a 'about' of the created link. In the 'about', I need to provide version info, authors, disclamers, affiliations and etc. To make it look nice, I need to make certain part of the text center aligned, and also insert a link of our affiliation. I'm using msgbox for this task at the moment. However, I coud not find a method to center align my text nor inserting hyperlink. Could someone help me with that?
thank you very much!

If you are using App Designer or creating apps with the uifigure function, then use uialert instead of msgbox.
The workaround is to build the message box yourself. Here's a demo that adds a blue, underlined text to a uifigure that, when clicked, opens a webpage (via a ButtonDownFcn callback function).
The "OK" button will close the figure.
% Create message box figure & axes
uifig = uifigure();
uiax = uiaxes(uifig,'Position',[0 0 uifig.Position(3:4)]);
uiax.Toolbar.Visible = 'off';
axis(uiax,'off')
% You don't need Latex interpreter if you're not underlining the link.
th = text(uiax, .5, .3, '$\mathrm{\underline{mathworks.com}}$',...
'color',[0 0 .8],'FontSize',20,'Interpreter','latex',...
'HorizontalAlignment','center');
th.ButtonDownFcn = @(~,~)web('mathworks.com'); % this opens the website
% Add OK button that closes figure
uibutton(uifig,'Text','Ok','Position',[50,50,75,30],'ButtonPushedFcn',@(h,~)delete(h.Parent))

There is no msgbox in this answer.
To add an image to a plot, first add an axes, then the image. Here's a demo.
There are additional ways to add an image if you're using AppDesigner (images can even be added to buttons).
If you have any other questions, please create a new question in the forum unless it pertains to this thread.
