This behavior change was indeed fallout from the major work we did to greatly enhance the basic mode support in 12b, giving the ability to read xlsx files on Mac and Linux, and Windows machines without Excel (among other goodies). WeвЂ™ve had a chance to look into this issue some more to try to understand what happened. Looks like some people may have forgotten the first rule and top commandment of engineering: No fewer than 54 comments (and counting) were added within a few days of the initial CSSM post, which indicates the amount of frustration that such changes cause. One such recent issue was raised over the documented removal of some functionality in the widely-used interp1 function. While the case with xlsread seems to break a new record in backward- incompatibility, other similar cases have also been reported. Still, considering the alternatives, this appears to be the best choice in my eyes. Of course, we would need to redo this fix in every future Matlab release as well. This will restore the previous functionality in one go, without having to modify any user programs. Specifically, comment line #45:Д¤3: % Trim the leading and trailing empties from textData 44: emptyTextMask = cellfun ( 'isempty', textData ) Д¤5: %textData = filterDataUsingMask(textData, emptyTextMask) % Comment out this line!Д¤3: % Trim the leading and trailing empties from textDataД¤4: emptyTextMask = cellfun('isempty', textData) A real shame.ДЄs an alternative to the official workaround above, I suggest modifying the %matlabroot%/toolbox/matlab/iofun/private/xlsreadSplitNumericAndText.m function, which is responsible for the functionality change. It causes such a maintenance headache that many users would simply prefer to remain with their older Matlab release, and not to upgrade. This tells us not to rely on the official release notes when deciding whether or not to upgrade. And what if the program needs to work on both R2012a AND earlier Matlab releases, which do not accept the вЂbasicвЂ™ input parameter? Or what if we need to use a range sub-set, which is unavailable in вЂbasicвЂ™ mode? Adding insult to injury, this change was never documented in the release notes, nor in xlsreadвЂs doc page. MathWorks cannot seriously expect thousands of Matlab users to change all their existing Matlab programs when upgrading to R2012a. Numerous Matlab programs rely on the existing functionality and behavior of xlsread. A major function such as xlsread, which is widely used by numerous Matlab users and has remained stable for years, can not вЂ“ MUST NOT! вЂ“ change existing functionality, with or without proper documentation. The main issue is backward compatibility. This is actually the lesser of the problems. The problem here is not only the missing documentation about the change in functionality. Unfortunately, this workaround leaves much to be desired. Note: the sheet-name is optional вЂ“ you can specify '' (an empty string) instead of 'Sheet1'. Our documentation was not updated with the change of behavior in xlsread. You obtain the same outputs dimension as in the previous releases.

= xlsread ( 'DeleteMe.xls', 'Sheet1', '', 'basic' )

This caused some trouble in our code and I want to forward this warning to other users.ДЇor example, letвЂ™s take the following simple Excel data file: This has the consequence that column numbers must be changed if you read from cell array txt. In Release 2012b these columns are missing at all. In case that the first columns of your Excel table have only numeric numbers, then the command = xlsread(.) returned in older Matlab releases for txt a cell array with blanks in the corresponding columns. To the best of my knowledge, this particular case was first detected by chance and reported by Andreas Pomp in CSSM last week, although the change was apparently already introduced in R2012a: As in the online URLs change, this change was also not documented, only adding to the frustration. Today I report on another such change, which has the potential of frustrating no fewer users. I already reported on a change to the online website that has gone largely unnoticed, which broke multiple links, causing much frustration. Among the many changes that were introduced in R2012b, the new desktop understandably took the centerpiece, with the new documentation layout coming a close second.
