What parse error? You forgot to include it. Show us all the red text.

Maybe try 'at' for a text file instead of 'a' in fopen().

That is not necessarily an error. The data could be retrieved from the file by using load() or readmatrix()

You would not typically save data to a .m file as .m files are normally for executable code.

If the expectation is that you are to create executable code, then you need to save the data in the form of an assignment statement. Something like

fid = fopen(etc etc);

fprintf(fid, 'ag = [\n');
now fprintf a and g
fprintf(fid, '];\n');

You would then do something similar for a1 g1, except giving it a different variable name, such as 'a1g1 = '
