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 Michael,

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 [comment reformatted for clarity- Doug] Hi,
