RandomRange从AFrom和ATo之间的范围中返回一个随机整数(不包含)。 RandomRange可以处理负范围(其中AFrom大于ATo)。 要初始化随机数生成器,请在对RandomRange进行任何调用之前,添加单个调用Randomize或为RandSeed变量指定一个值。 例如: 1 RandomRange(1,10);//返回1-9的数字,不包含10...
Delphi Random() 随机函数 函数原型:function Random ( Range: Integer) :integer; 参数:Range:整数, 返回值:整数,其范围为: 0 <= Random(Range) < Range (指定Range) 0 <= Random< 1 (不带参数Range) Random()生成随机数。(运行几次会发现取得的随机数一样,因为系统的随机种子没有改变,Ramdomize; 用来...

(9)]. Then, z can be mapped to any given variation range since the correlation is invariant to linear transformations. Instead of adding an error term to the y values, another approach is to multiply the y values by a random coefficient α that varies in an appropriate way. Thus, the ...
