matlab -r in shell not work

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.

This code will open a new instance of Matlab. Did you expect it to execute in an already opened instance?

[PanZhang Zhang]

new one or an opened instance both ok for me. only if it can execute my script

[Steven Lord]

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.

[PanZhang Zhang]

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'.
