| Key | Default Value | Options | Description |
| simplex | |||
| FUNCTION | '' | none | Function handle to minimize. |
| X0 | [] | none | The starting point. |
| DISPLAY | 'iter' |
|
Level of display.. |
| FUNVALCHECK | 'off' |
|
Check whether objective function values are valid. 'on' displays an error when the objective function returns a value that is complex, Inf or NaN. 'off' (the default) displays no error. |
| MAXFUNEVALS | 1000 | none | Maximum number of function evaluations allowed. |
| MAXITER | 1000 | none | Maximum number of iterations allowed. |
| OUTPUTFCN | [] | none | User-defined function that is called at each iteration. |
| PLOTFCNS | [] | none | Plots various measures of progress while the algorithm executes. |
| TOLFUN | 1.0000000000000001e-05 | none | Termination tolerance on the function value. |
| TOLX | 1.0000000000000001e-05 | none | Termination tolerance on x. |
| FITPARAMS | '' | none | The names of the parameters to fit. |
| TXT | 0 |
|
Set to true if a print of the parameters into a txt file is desired. |
