This modification of fminsearch solves an issue with this simplex implementation when the function to minimize is smooth at a high scale, but rough at a low scale, i.e. when plotted with the parameters axis being (?10,10), there is a clear global extremum, but when zoomed (-0.1,0.1), the function...
