matlab中self.

在MATLAB中，self是一个指向当前对象的指针，可以用来访问对象的属性和方法。在类的方法中，可以使用self来引用当前对象的属性和方法。

例如，如果有一个类叫做MyClass，其中有一个属性叫做myProperty，可以在类的方法中使用self来访问这个属性：

classdef MyClass
    properties
        myProperty
    end
    
    methods
        function myMethod(obj)
            % 使用self来访问myProperty
            disp(self.myProperty);
        end
    end
end

转成matlab：self.eta = self.eta_max if kwargs.get('first_iter',False) and not self.linesearch_first: self.eta = kwargs.get('eta_first',1) loss_diff = 1 while loss_diff > 0: loss_diff, temp_embedding, delta = self._linesearch_once( update_embedding_with,grad,calc_loss,loss,**kwargs) if self.eta <= self.eta_min and loss_diff > 0: loss_diff, temp_embedding, delta = self._linesearch_once( update_embedding_with,grad,calc_loss,loss,**kwargs) loss_diff = -1 self.eta *= 2 update_embedding_with(new_embedding=temp_embedding) return delta

self.eta = self.eta_max;
if isfield(kwargs,'first_iter') && kwargs.first_iter && ~self.linesearch_first
self.eta = kwargs.eta_first;
end
