Query the value of the property field in the ODE options structure ode_opt.
If called with two input arguments and the first input argument ode_opt is an ODE option structure and the second input argument field is a string specifying an option name, then return the option value val corresponding to field from ode_opt.
If called with an optional third input argument, and field is not set in the structure ode_opt, then return the default value default instead.
See also: odeset.
The following code
## Return the manually changed value RelTol of the ODE options ## structure A. If RelTol wouldn't have been changed then an ## empty matrix value would have been returned. A = odeset ("RelTol", 1e-1, "AbsTol", 1e-2); odeget (A, "RelTol", [])
Produces the following output
ans = 0.10000
