I run matlab 2018a on ubuntu 16.04.
When I open gui and run the code, I got result 0.86
When I use no gui
screen
matlab -nodisplay -nodesktop -nosplash <t2_esc.m> t2_esc.txt &
screen -d
I got result 0.93
That is exactly the same code. Does anyone know why?
By the way, specific random seed, rng(0)

I just wondered, will the value of t2_esc.txt considered as char put into your function t2_esc.m?

No, t2_esc.txt is a log file, the output of command window.

There is no magic flag for changing the results if Matlab is called without GUI. Therefore you can be sure that you instruct Matlab to calculate something different. Perhaps you have two different files called t2_esc.m, so if Matlab starts without GUI you are in a different folder and process another file. Or the calculations include a dependency to the settings of the GUI. Without seeing the code it is impossible to guess the reasons.
Do these two calls reply the same results?
matlab -nodisplay -nodesktop -nosplash <t2_esc.m> t2_esc_a.txt &
matlab <t2_esc.m> t2_esc_b.txt &

I just tried your suggestion and both gives me 0.93, with the following commands,
matlab -nodisplay -nodesktop -nosplash <t2_esc.m> t2_esc_a.txt &
matlab <t2_esc.m> t2_esc_b.txt &
but I if I open matlab using
matlab &
and open t2_esc.m and hit F5.
it still gives me 0.86

Then add this to the function:
disp(mfilename('fullpath'))
to show, if you really use the same files.
What about:
matlab -r "t2_esc" &
