“Profile to Improve Performance”dosen't work well on matlab2019a

It seems that the profiler UI dose not work well on my matlab2019a, which is an academic use version of matlab2019a bought by Wuhan University, China.

I tried to run the matlab code below on matlab2016a and matlab2019a, respectively.

**

profile on

[t,y] = ode23('lotka',[0 2],[20;20]);

profile viewer

**

Then, the corresponding outputs shown in user interfaces are shown as follows.
