Description: Hough变换用来在图象中查找直线。它的原理是：假设有一条与原点距离为s，方向角为θ的一条直线，直线上的每一点都满足方程 s=x*Cosθ+y*Sinθ，利用这个事实，我们可以找出某条直线来。这段程序，用来找出图象中最长的直线。-Hough Transformation is used for searching lines in an image . Here is the principle:
Assume there is a line whoes direction is \"sita\" , and the distance from the origin to this line is s. So each point in this line satisfies the equation : s=x*Cos(sita) + y*Sin(sita) . We can find out the lines based on this fact.
And this programme is to find out the longest line in the image.

Description: Finds the polynomial p10 of degree less than or equal to 10 that interpolates
cos x on the interval [0, PI/2] at 11 equally spaced points. Study the error betwee
between the function and the polynomial at 41 equally spaced points over the
same interval. Repeat the latter but use your 11 points to be Chebyshevs.

Description: 现有一个信号：x(n)=1+cos(π*n/4)+ cos(2*π*n/3)设计及各种数字滤波器以达下列目的：
低通滤波器，滤除cos(2*π*n/3) 的成分，即想保留的成分为1+cos(π*n/4)
高通滤波器，滤除1+cos(π*n/4) 的成分，即想保留的成分为cos(2*π*n/3)
带通滤波器，滤除1+cos(2*π*n/3) 的成分，即想保留的成分为cos(π*n/4)
带阻滤波器，滤除cos(π*n/4) 的成分，即想保留的成分为1+cos(2*π*n/3)
1. 用MATLAB命令butterord求除滤波器的阶数,用命令butter设计各滤波器；画出滤波器幅度和相频相应 取各滤波器的系统函数H(z)。

sin(21-32)/(12-43)
4(323-4343) 4*(323-4343) e^2-sin3-3^4,(不要输入pow(3,4)) //有无*都可
2*3^4是（2*3）^4 而不是2*(3^4) 也就是要用x^y就要一定要（x^y）加上一个括号
[3-4]是求3-4的绝对值不是中括号 -performance computing functions : sin, cos, tg, rays, e ^, pow (x, y), cosh, sinh, tgh, log10, ln, sqrt, Simulation, arccos computational methods : absolute ,-,*,/, ( "[]"),^,!, importation rules : a keyboard or buttons which can be imported by the transport operator End (cursor to the final) sin (21-32) / (12-43) 4 (323-4343) 4 * ( 323-4343), e ^ 2 - KF-3 ^ 4 (do not enter pow (3,4)) / / * there can be 2 * 3 ^ 4 is (2 * 3) ^ 4 rather than 2 * (3 ^ 4) was needed x ^ y must have (x ^ y) with a brackets [3-4] is the pursuit of 3-4 is not the absolute value of the brackets

Description: 这是一个基于表达式的科学计算器，计算结果的有效位较长（16位）；支持不严格的表达式输入（如cos(23)*sin(34)与cos(23)*sin(34与cos23*sin34等价）；支持四种进制的数在一个表达式中同时出现的进制混合运算（除十进制外的各进制数不限于整数，如12d.3axh，xh是我的计算类所能识别的十六进制数的标识符）；且程序做得也比较精细（如制作了鼠标键盘、窗口跟随、计算历史查看等），功能非常不错。-This is a formula based on the scientific calculator, the results effectively place a longer period (16); Support rigorous expression input (such as cos (23) * sin (34) and cos (23) * sin (34 with the equivalent sin34 cos23 *); support for the four band in a few expressions while the band mixed computing (except for the metric system outside the band is not limited to a few integers, as 12d.3axh, xh I kind of calculation can identify the hexadecimal number identifier); the program also doing fine (as produced by the mouse and keyboard , the window to follow the history of computing View), which is very good.
