Matlab(short for MATrix LABoratory)is a special-purpose computer program optimized to perform engineering ang scientific calculations.It started life as a program designed to perform matrix mathematics,but over the years it has grown into a flexible computing system capable of solving essentially any technical problem.
The MATLAB program implement the MATLAB language,and provides a very extensive library of predefined functions to make technical programming tasks easier and more efficient.This extremely wide variety of functions makes it much easier to solve technical problems in MATLAB than in other languages such as Fortran or C.This book introduces the MATLB language ,and shows how to use it to solve typical technical problems.
This book teaches MATLAB as a technical programming language,showing students how to write clean,efficient,and well-documented programs.It makes no pretense at being a complete description of all of MATLAB’s hundreds of functions.Instead,it teaches the student how to use MATLAB as alanguage,and how to locate any desired function with MATLAB’s extensive online help facilities.
The first six chapters of the text are designed to serve as the text for an”Introduction to Programming/Problem Solving”course for freshman engineering students.This material should fit comfortably into a 9-week,3-hour course.The remaining chapters cover advanced topics such as input/outpunt and graphical user interfaces.These chapters may be covered in alonger course,or used as a reference by engineering students or practicing engineers who use MATLAB as a part of their coursework or employment.

A crossword can be stored as a matrix m x n of zeros and ones.Zero represents white squares and one represents black squares.Some squares of the crossword are numbered and assigned to these numbers are the descriptions of the words that should be written either ``across'' or ``down'' into the crossword.A square is numbered if it is a white square and either (a) the square below it is white and there is no white square immediately above,or (b) there is no white square immediately to its left and the square to its right is white.The squares are numbered from left to right,from the top line to the bottom line.
From the matrix a crossword diagram can be drawn.In the diagram each square is represented by a box 4 x 6 characters.Black square and white squares (numbered and not numbered square) are represented as follows (where nnn is the number of the square):
++++++ ++++++ ++++++
++++++ +nnn + + +
++++++ + + + +
++++++ ++++++ ++++++
The remaining characters of the box are spaces.If black squares are given at the edges,they should be removed from the diagram (see the example).Only use spaces as necessary filling characters.Don't use any unnecessary spaces at the end of the line.
Input
The input consists of several blocks of lines each representing a crossword.Each block starts with the line containing two integers m < 25 and n < 25 separated by one space.In each of the next m lines there are n numbers 0 or 1,separated by one space.The last block will be empty,m = n = 0.
Output
The output contains the corresponding crossword diagram for each except the last block.After each diagram there is two empty lines.

绝对高分求教MATLAB实现Hessian Matrix（海森矩阵）的计算,
图片是我要求Hessian Matrix的式子,其中W,C和那个误差（ε Epsilon）是我要求偏导的变量,其中W是204*1（对应X的行数）,C是1*1,ε是240*1（对应X的列数）,这三个和在一起构成一个变量向量Z = 445*1,这里面的数值时已知的.X是已知的矩阵204*240,Xi就是每一列.如果您做过SVM可能已经开出来这就是SVM 支持向量积了.我现在要做的就是求这个式子的梯度和hessian matrix,并且把Z 中的值带回去,因为这个式子最高就是WT*W是二次,所以hessian matrix肯定可以化为具体数字.这个hessian matrix应该是445*445大小.

Line,staff and matrix organization
The main departments of an organization reflect the key functions on which it reles.A typical manufacturing firm will have (at least) production,purchasing,accounts and sales departments.The system of organization based on these functions is known as line organization.The advantages of line organizations are that responsibilities are well-defined and understood,and the simple nature of the structure does not inhibit communication.
As they grow in size,organizations come to rely more heavily on specialist functions and personal.A good illustration is the developed nature of the personal function in medium-sized and large firms.A line and staff organization recognizes the importance of such specialists,although these problems can arise:
 A lack of ‘line’understanding of ‘staff’techniques,procedures and language;
 Some line managers feeling inhibited or threatened by the existence and work of the ‘staff’specials;
 Communication slowing down due to the increased complexity of the organization structure.
