After installing Matlab R2018b in Fedora 29, whenever I tried to launch the documentation help window with the command:

>> doc VideoReader

The documentation browser appears with its content unformatted:

There are some solutions in the web that suggest:

Installing libnsl
Use the libfreetype fonts from the operating system rather than the ones distributed as part of Matlab R2018b
Use the system libcrypto from the OS

However, none of the above work. Moreover, when I run "!ldd ~/opt/matlab/r2018b/sys/jxbrowser-chromium/glnxa64/chromium/jxbrowser-chromium" from the matlab console, all the required libraries are correctly linked.

Any suggestions?

This is caused by missing libraries or missing execution permission. To narrow it down do the following:

1.) Start MATLAB

2.) execute

>> com.mathworks.mde.webbrowser.HtmlPanelDebugConsole.invoke;

3.) Open the help by executing

>>doc

The output generated in the Browser Log, Chromium Log and IPC Log tab will have more information regarding the cause of this issue. View the logs and you can rectify the issue.
