run function from command line

I want to start a matlab function from the unix command line. For now I use

matlab -nodisplay -r "functionname(argument1, argument2, argumentN);exit"

But for this the function I call needs to be in the folder where I am. Is there a way to call the function like

matlab -nodisplay -r "/path/to/functionname(argument1, argument2, argumentN);exit"

without manually adding it to the search path of matlab?

Do you mean:

matlab -nodisplay -r "cd('/path/to'); functionname(argument1, argument2, argumentN);exit"

Thank you very much for helping. This easily solved my problem.

Does this change the directory that you are in permanantly or does it cd back after this command is called?

Thank you Mr. Jan. Seems like windows prompt is slightly the same with unix haha.

Someone might be needing this: For windows command prompt, I used the command : "C:\Program Files\Polyspace\R2021a\bin\matlab.exe" -nosplash -nodesktop -r "cd('D:\matlab_project\scripts\'), testFnc('blah'), exit"

with my testFnc.m

function sample = testFnc(stri)

sample = stri

disp(sample)

end

FWIW, this does seem to cd back to the original directory after MATLAB exits

I'm not 100% sure this option was available in releases R2017a or R2017b, but I'm pretty sure it was. Use the -sd startup option to cause MATLAB to start in a certain directory.
