I have one specific line of code that I can't type in or edit whatsoever and I need to because I'm being graded on it by Matlab grader for a class.

I can't edit this line of code no matter what I do to the extent that when I click on it instead of my cursor blinking being ready to type it remains solid. I can't even hit the enter key in the line.

My understanding is that MATLAB grader assignments consist of a mix of lines that are not editable, together with lines that are intended to be edited.

For example the code might have an editable block that looks something like

signal = ?;
bits = ?;
method = '?';

followed by an uneditable call

encoded_result = encode_signal(signal, bits, method);

with the intention being that you fill out appropriate values in place of the ? and then there is a fixed unalterable code to encode_signal

Can you edit other lines in the assignment?

If the line is gray, it is locked and you can't edit it. If you are expected to redefine a value in that locked line, you can do so by going to an unlocked line below it and making the change there.
