Would someone be able to help me with a rather simple script I have to write? The script needs to be able to take a text file and count the number of lines of text. Any help is greatly appreciated!

Why do you need to count the number of lines in a text file here? Many simple word processors are capable of displaying this type of information.
If you do still want a script to specifically do this, see my response to your other question about capturing certain words.

Is newline to be considered a line terminator or a line separator? If it is a line separator then if the last thing in a file is a newline then the emptiness between the newline and the end of file counts as a line.

linecount = sum(fileread(somefile) == 10) + 1;
See Walter's comment. This will count the emptiness between the newline and end of file as a line if the last line ends in a newline.
Will works both for Windows and Linux line ending (but not old style macs which used char(13) solely as a newline marker).

Try this
textLines = readlines(fileName);
numLines = numel(textlines)

That question is not related to the question of how to accurately count lines in a text file. You should start your own question.

Okay, thank you, I will post my question above. The information I want to extract is how the object changes the illuminated light when reflected by adding some harmonics to the original sinusoid
