Undefined function or variable in Matlab when calling a function from cmd

Question

I have a function in Matlab like this:

function func(v1)
v1
end

and I want to call it from cmd. so when I call it in cmd with command like

matlab -nodisplay -r "func("hello");"

I face an error:

Undefined function or variable 'hello'.

but I just want to have string "hello" in my function.

when I try a function which has not any argument, it works properly. but the error occurs when I want to pass argument to the function.

any help will be appreciated.

You want to use single quotes here:

matlab -nodisplay -r "func('hello');"

when I want to call the function from another directory, I use command like >matlab -r "D:/matlab_function/func('hello');" and I get the error --> Error: Invalid use of operator. how should I set the command here

@ali Don't do that, use the sd flag to change directory

I meant sd. See mathworks.com/help/matlab/ref/matlabwindows.html
