I am using windows 10 and Matlab 2018b. I have a code was run fast, but suddenly it become so slow. The pseudo code of my code is as follows:
for i=1 : 200
for j=1 : 200
for k=1 : 200
NewMatrix = Archive(i,j)*Archive(k,j) + Archive(j,k)
where the Archive is a matrix of [200,6]
I don't know where is the problem. I am using CPU. could you help me please ?

Hi Rahim,
One thing worth checking is, with windows 10 bring up the task mananger, click the Perfomance tab, start the program and see what the memory, disk and possibly cpu activity looks like as a function of time.

Please spend some time reading the documentation for that function.
You need to follow the second example, "Profile Function and Save Results as HTML".
Then you need to view the reports and compare them.
And don't forget to take time to formally accept answers that were helpful to you so you can give credit to the volunteers who gave their time to you. This isn't an answer, it's just a comment, but you can go into your profile and see many questions that have been answered and none accepted.
