摘要
在数值逼近中,有时数据是随机给出的,研究此类逼近问题具有一定意义。利用概率论中数学期望可以刻画出随机变量取值的平均数这一特性,构造出一种新的函数列,在离散型随机函数的情况下,讨论了其对随机函数的依P概率逼近问题。
It is of great significance to study the approximation problems of the random functions. A new functional sequence is formed by the use of the property that in probability theory, mathematical expectation can characterizes the average of the random variables. When the random functions are discrete, the P probability approximation problems of them are discussed.
