说明: (拟合)
用给定的多项式,y=x3-6x2+5x-3,产生一组数据(xi,yi,i=1,2,…,n),再在yi上添加随机干扰(可用rand产生(0,1)均匀分布随机数,或用rands产生N(0,1)分布随机数),然后用xi和添加了随机干扰的yi作的3次多项式拟合,与原系数比较。
如果作2或4次多项式拟合,结果如何?
((Fitting) with a given polynomial, y = x3-6x2+5 x-3, generated a set of data (xi, yi, i = 1,2, ..., n), then add a random disturbance yi ( can be generated rand (0,1) uniformly distributed random number, or rands generated N (0,1) distribution of random numbers), and then added with xi and yi for random interference of the 3 times polynomial fitting, and the original coefficient. If 2 or 4 times for polynomial fitting, the result?)

TotalMemory
用来测试手机待机情况下所能使用的最大内存量,普通用函数调用得到的剩于内存是错误的,这个通过用INT占用内存来获得可以使用的内存真正空间大小(Used to test mobile phone standby cases the maximum amount of memory can be used by the general use function calls get left in the memory is wrong, it occupied by the memory by using INT can be used to obtain the real memory space)
