octave: scripts/ode/ode15s.m annotate

annotate scripts/ode/ode15s.m @ 28041:5e44268dca6f

Replace input validation relying on str2func with alternatives (bug #57351). * ode15i.m, ode15s.m, ode23.m, ode45.m, check_default_input.m: Replace try/catch blocks around str2func with a call to exist() to check whether function exists before calling str2func.
