Hi all, I am writing a code that need to be able to find the particular row number in a large nx3 matrix (where n will eventually be >100000). I created a line of code to accomplish this task, but above n=20000 it does not work. Each row is unique (the matrix will never repeat a line).
row_num = max(find(ismember(pts,[X Y Z],'rows'))
Does anyone know of a way to run this where it will function at a higher n value.
edit: pts is the name of the nx3 matrix
edit: ismember is causing the problem (it is acting like it has a size limit)
