qp.m: Overhaul function (fixes bug #45324). * qp.m: Put input validation first. Validate both x0 and q are vectors. Transform x0 and q to column vectors for rest of computation (bug #45324). Use double quotes instead of single to match Octave coding conventions. Re-wrap multi-line comments to break at meaningful boundaries. Use isargout to avoid calculating unnecessary outputs.
