I have shell script naming test.sh with code like follows in it:

matlab -nodisplay -nosplash -nodesktop /r "test('$a','$b')"

then i run the test.sh in windows10, the matlab command windows is opened but my matlab function test not execute in the window. I want to know why, and how to fix it.

What does "not execute" mean in this context?

Do you receive warning and/or error messages? If so the full and exact text of those messages (all the text displayed in orange and/or red in the Command Window) may be useful in determining what's going on and how to avoid the warning and/or error.
Does it do something different than what you expected? If so, what did it do and what did you expect it to do?
Did MATLAB crash? If so please send the crash log file (with a description of what you were running or doing in MATLAB when the crash occured) to Technical Support so we can investigate.

在 MATLAB Online 中打开

for example,here is my test.m file content:

function test(a,b)
    c=a+b;
    disp(c);
end

when i run command: matlab -nodisplay -nosplash -nodesktop /r "test(1,2)" in powershell,

it opens a matlab command window, and showing result "3" on a new line in the window,

but when i run the same command in a shell script. it just opened a new matlab command window,then nothing happened just like my function test in the test.m without running.

about your confusion:

I did not get any warning or error messages.
I expect the test function will be performed in the opened matlab command window,the result 'c' should be displayed in the window.
Matlab not crashed, the command window should be able to run matlab command without opening matlab main ui when with argument '-nodesktop'.
