You can use one of the interpolation functions like interp1,

interp2, interpn, and spline. Depending on the behavior of

data, you may want to specify a certain type of interpolation

like linear, pchip, or spline. Splines have a tendency to

oscillate when there shouldn't be any oscillations.

You need to write a function that fminmax will call. Inside

this function, use the interpolation functions to fit the data.

You may want to create a persistent variable inside this function

to hold the data (read in once), hard code it in, or read it in

every call. I would use the persistent variable.
