Hello everyone,
I am currently looking for a function that would return the index of identical row in 2 different array. I tried with
listIdx=ismember(conversion,x,"rows");
out=find(listIdx);
However it need a lot of time to get the result: ~0.7s 0.8s for 1 element when I can have more than 600 rows to compare.
I also trye ismembc function but it compare all the single elements of both array
Is there a faster way to that ?
Thank you in advance for your help
Mathieu

Ok I did not know that.
However when I try to load the .dll file like this :
loadlibrary('IsMemberRows.dll')
I have the following error
Unrecognized function or variable 'IsMemberRows_proto'.
Maybe I am doing something wrong because I have all the downloaded files in the same folder

No, I don't think you are doing anything wrong: the chance that a DLL created 23 years ago will run on your computer is slim. Unless someone knows how to make it work, we should consider that FEX submission as abandoned.
