  • [Octave] optimset()

    Create options struct for optimization functions.

     

    optimset('parameter', value, ...);
    %设置所有参数及其值,未设置的为默认值
    
    optimset(optimfun);
    %设置与最优化函数有关的参数为默认
    
    optimset(old, 'parmeter', 'value', ... );
    %复制已有的设置,并修改特定项
    
    optimset(old, new);
    %两项合并
    

      

    GradObj

    When set to "on", the function to be minimized must return a second argument which is the gradient, or first derivative, of the function at the point X.  If set to "off" [default], the gradient is computed via finite differences.

     

     

    MaxIter

    Maximum number of algorithm iterations before optimization stops.  Must be a positive integer.
