Which Version support the new syntax of try statement

I used try function to solve the question with following format: try statements catch exception %here statements end

When this program run in Matlab R2011b, it is OK. But it doesn't work in MATLAB 7.0.

Which version of MATLAB is support the below format with "exception".

[Andreas Goser]

To my best knowledge, your issue is not related to version compatibilty. CAn you share the code that is not working in MATLAB 7.0?

Qingping commented

A=rand(3,3);
B=rand(2,2);
try
  C = [A; B];
catch err
  if strcmp(err.identifier,'MATLAB:catenate:dimensionMismatch')
    C={A;B}
  end
end
C

MATLAB 7.4, R2007a was the first version to support the newer syntax.

thanks.

can you tell me how to found your answer? because i want to find which version support "ftp" function?

[Andreas Goser]

In general, you may find this information in the release notes, but that can be cumbersome. MathWorks support engineers obviously have all access to all releases. For the FTP example. I had a look at the doc archive (you need to be linked to a license with maintenance to be able to see that:

http://www.mathworks.com/help/doc-archives.html

Then I checked R13SP2 (FTP not in), then R2006b (it is in). The you can find it in an iterative way...

my code is Similar with the following code:

    A=rand(3,3);    %3*3 matrix
    B=rand(2,2);      %2*2 matrix
    try
       C = [A; B];
    catch err
      if strcmp(err.identifier,'MATLAB:catenate:dimensionMismatch')
        C={A;B}
      end
    end
    C
