i use that function to check if data from one set is member of other set.

could you help me Mr

best regard

I just tested this in the manner you described it. I saw no slowdown on the if statements. Please send the code into tech support and we will see what they can do for you.

Thanks,
Doug

Great video,
actually I have a problem.
The profiler shows some “if” statements that
take a lot of time, (simple ifs like if a == 1), other ifs
and ends take 6 seconds.

About end statements, I understand from previous guys
but why if statements are so slow, I just want to know if it is some kind of a bug or it is a MATLAB limitation ?

Hope to get an answer,
Thanks
