The mahalanobis distance in Character Recognition Authored by Dan Frey 31 July 98 This sheet explores the use of the Mahalanobis Distance in character It defines a letters a.b.c. and d It creates a population of distorted letters to train a classifier

Directions: In this section, you will hear ten short conversations At the end of each conversation, a question will be asked about what was said. Both the conversation and the question will be spoken only once. After each question there will be a pause. During the pause, you must read the four choices marked A), B), C)and d),and decide which is the best answer. Then mark the corresponding letter on the Answer Sheet with a single line through

1 Faraday's law of electromagnetic induction 1. Experiments ① A magnet and ② two loops of wire,a loop of wire battery and a switch A current is observed in the loop as long as the magnetic flux through the loop is changing with time

1.证明:若微分方程xy\+y+xy=0有多项式解 y=a+a1x+a2x2+…+anx, 则必有a1=0(i=1,2,…,n)

我们在中学里已经遇到过级数一一等差数列与等比数列,它们都属于项数为有限的特殊情形。下 面我们来学习项数为无限的级数,称为无穷级数 无穷级数的概念 设已给数列a,a2,…,a,…把数列中各项依次用加号连接起来的式子an+a2+…+an+…称为无穷 级数

一、矩阵序列 1.定义:设有矩阵序列{A},其中A=(a),且当k时aa,则称A收

一、一组变量,名字相同,数据类型相同,用下标(索引-Index)来区分。例如:a(0),a(1),…,a(n)H称为数组a的成员(元素、下标变量) 二、两种类型的数组: 1 静态数组:成员数量不变 2 动态数组:成员数量可变
