How can I reduce the run time a code?

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);
