Key	Default Value	Options	Description
simplex
FUNCTION	''	none	Function handle to minimize.
X0	[]	none	The starting point.
DISPLAY	'iter'	'iter' 'off' 'notify' 'final'	Level of display..
FUNVALCHECK	'off'	'off' 'on'	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	0 1	Set to true if a print of the parameters into a txt file is desired.
