Optimset

FMINLBFGS is a Memory efficient optimizer for problems such as image registration with large amounts of unknowns, and cpu-expensive gradients.Supported:- Quasi Newton Broydend-deOCtFletcherd-deOCtGoldfarbd-deOCtShanno (BFGS).- Limited memory BFGS (L-BFGS).- Steepest Gradient Descent...

Often one desires to write a function that takes a large number of optional arguments. One way to do this is to allow for an arbitrary number of option name-value pairs in the function argument:function r = f(a,b,c,name1,value1,...)This method has the advantages of:1) Allowing those using the...

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...
