Opening the textfile with the row of data:
app.T = readtable(filename, 'Delimiter', 'space');
Error using readtable (line 245)
"filename" must be a string scalar or character vector.
Editting the numbers:
app.T.ct(1) = app.ctEditField.Value;
Saving the new values:
Q = app.T{:,1};
fileid = fopen('name.txt');
fprintf(fileid, '%f\n' , Q);
fclose(fileid);
I am still getting an error with this process. I think it must be how the numbers are represented. There is also a chance that I may not be editting the numbers correctly.
