matlab -batch always failed with: | Error: Invalid use of operator.

Following Matlab's manual, I run Matlab with: matlab -batch ./hello.m or matlab -batch "./hello.m".

However, there is an error: | Error: Invalid use of operator.

The hello.m is just an oneline script: fprintf("hello\n");

Can you tell me what is the problem here?

Thanks!

The string after the -batch argument must contain a Matlab command. "./hello.m" is not a Matlab command, because "./" is the elementwise division. You do not specify paths of Matlab functions, if you call them. The appended ".m" let Matlab assume that "hello" is a struct.

Try this instead:

matlab -batch "hello"

Remember to store the file hello.m in a folder, which is included in the Matlab path.
