Hi! After updating to Version 2016b the xlsread function gives out following error:

Error using xlsread (line 249)
Error: File: xlsreadCOM.m Line: 113 Column: 12
Arguments to IMPORT must either end with ".*" or else specify a fully qualified class name:
"matlab.io.spreadsheet.internal.columnLetter" fails this test.

With the Version 2015b the function worked fine! Can anyone help?

Thanks a lot. Cheers, Chris

Steven's code give the same result on my R2016a

C:\Program Files\MATLAB\R2016a\toolbox\matlab\iofun\xlsread.m
'matlab.io.spreadsheet.internal.columnLetter' not found.
isOnPath =
     []
>> version
ans =
9.0.0.341360 (R2016a)

For me, a full deinstall and reinstall of 2016b solved this problem. The code from Steve no longer results in an empty value.

Try to restore Matlab path to its default with the commands:

>> restoredefaultpath

>> rehash toolboxcache

>> savepath

I had exactly the same problem as yours and restoring the path solved it.

This also solves my error:

Error using print (line 83)
Error: File: datestr.m Line: 126 Column: 8
The import statement 'import matlab.internal.datatypes.stringToLegacyText' cannot be found or cannot be imported. Imported
