ismember legacy flag with older Matlab
显示 更早的评论
If I use the legacy flag of ismember function in Matlab prior to 2012b like this
if ismember(A,B,'rows','legacy') do something... end
I get too many input arguments -error.
I'd like my code to work on both, earlier and newer Matlabs so how can omit the legacy flag if older matlab is used. I really don't want to make separate if-clauses in case of older and newer versions because there are so many of them.

Hi,
an IF clause is the only way here.
You could write your own small helper function which calls ismember and deals with the versions. So something like (haven't actually tried it but something like this should do it):
function [Lia,Locb] = myismember(A,B,flag)
if flag_was_provided AND MATLAB_version_is_smaller_than_8
[Lia,Locb] = ismember(A,B)
else
[Lia,Locb] = ismember(A,B,flag)
end
end

But the built in functions in 14a are not the same in 12a or so. Saying that the image function in 12a does not pass down the 'legacy' flag. So you don't have to worry about that.
You would need to adjust your code only and replace your ismember call with a dummy function which handles the argument conversion. Basically do NOT overload ismember. Only adjust your code to not call ismember directly.
