I am trying to run a code which used to work perfectly using previous versions of Matlab. Now after upgrading to version 2015b I receive this error at line 251 of xlsread.m
I've battled this stupid error for too many hours, and only foundone clue to what seemed to be the problem: Excel add-ins! Looking at the error message, I got the code 'MATLAB:COM:E0'. I looked in the add-ins section in Excel's options and what you know, FoxIt reader has installed an add-in that has to do with Excel's COM interface. I disabled it, restarted MATLAB and the error was gone!
This also solved the problem I had with xlsread(), which forced me to use the 'basic' parameter otherwise it wouldn't read any file.
