optimset — Create or update optimization options structures with MATLAB-compatible name/value handling.
optimset builds option structs for optimization routines and supports MATLAB-compatible create-from-scratch and copy-and-override workflows with recognized option names.
Syntax
options = optimset()
options = optimset(name, value, ...)
options = optimset(oldopts, name, value, ...)Inputs
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
name | Any | Yes | — | Option field name. |
value | Any | Yes | — | Option value. |
oldopts | Any | Yes | — | Existing options struct to update. |
name | Any | No | — | Option field name. |
value | Any | Variadic | — | Option value(s) and additional name/value pairs. |
Returns
| Name | Type | Description |
|---|---|---|
options | Any | Options struct for optimization solvers. |
Errors
| Identifier | When | Message |
|---|---|---|
RunMat:optimset:InvalidArgument | Name/value argument grammar is invalid. | optimset: invalid argument |
RunMat:optimset:InvalidInput | Option field names are not valid string scalars. | optimset: invalid input |
How optimset works
- Option names are case-insensitive for the builtins that consume them.
TolX,TolFun,MaxIter,MaxFunEvals, andDisplayare canonicalized when constructed withoptimset.- Unknown option names are preserved so future solvers can read them.
Example
Create options for fminbnd
opts = optimset('TolX', 1e-10, 'Display', 'off');
x = fminbnd(@cos, 0, pi, opts)Expected output:
x =

Open a RunMat example with live inputs, then ask the agent to explain how optimset changes the result.
Run a small optimset example, explain the result, then change one input and compare the output.
