Creates a DownhillSolver object.

solver = cv.DownhillSolver()
solver = cv.DownhillSolver('OptionName', optionValue, ...)

Options

• Function Objective function that will be minimized, specified as a structure with the following fields:
  • dims Number of dimensions
  • fun string, name of M-file that implements the calc() method. It should receive a vector of the specified dimension, and return a scalar value of the objective function evaluated at that point.
• InitStep Initial step, that will be used to construct the initial simplex. default [1, 1, 0.0].
• TermCriteria Terminal criteria to the algorithm. default struct('type','Count+EPS', 'maxCount',5000, 'epsilon',1e-6)

All the parameters are optional, so this procedure can be called even without parameters at all. In this case, the default values will be used. As default value for terminal criteria are the only sensible ones, ObjectiveFunction and InitStep should be set upon the obtained object, if the respective parameters were not given in the constructor. Otherwise, the two ways (give them to ctor or miss them out and set the ObjectiveFunction and InitStep properties) are absolutely equivalent (and will drop the same errors in the same way, should invalid input be detected).
