Hi everybody,
I ran a code and controlled the run time of each script.
As you can see in Figure attachment, I realized that find command increase the run time.
How can I reduce this time?

Directly use logical indexing , i.e: remove find(…) command and replace your if condition with
if any(index)
Try using ismember(…) instead of == , not sure which one is faster.

Replace the whole for-loop over y with,
index_control=ismember(aktivite1, aktivite2);
m=find(index_control,1);
index_control(m+1:end)=0;
bxf2(j)=~isempty(m);
