Good evening Philip

I have JAVA x64 installed, see below:

steph@sjb-pc:$ java -version
openjdk version "11.0.6" 2020-01-14
OpenJDK Runtime Environment (build 11.0.6+10-post-Ubuntu-1ubuntu118.04.1)
OpenJDK 64-Bit Server VM (build 11.0.6+10-post-Ubuntu-1ubuntu118.04.1, 
mixed mode, sharing)

I have implemented workaround, see below:

datMC = xlsread(Fname,SheetName, '', "oct");

As far as I can see the read is fine and the JAVA message disappeared 
altogether!

Thanks for help, let me know if I can help you with something.

Regards

Steph
