You tried

data_autokorr = xlsread ('file.xlsx', 'A16:C271');

but better do

[data_autokorr, ~, rawdata] = xlsread ('file.xlsx', 'A16:C271');

The cell array rawdata will hold all data (numeric and text) so you can see
what format your first column was in the Excel file. Like Markus I suspect
it is text.

As to the error message about Java package, that is really looks outdated;
what does "pkg describe io" say? 
I'll look into that but later, I'm abroad with patchy Internet access and
little time until after early August.
