用脉冲响应不变设计巴特沃斯数字低通滤波器(Designed by the same impulse response digital low-pass filter Butterworth)

是粒子群算法的MATLAB源程序，可以在matlab中运行(Is the source of the particle swarm algorithm in MATLAB, you can run in matlab)

Rosen梯度投影法解约束优化问题minf（x）；Ax>b 的算法，其中约束条件为线性约束，A为约束系数矩阵，b为约束向量。基本思路是从可行点出发，沿着目标函数减小的方向搜索求出新的可行点，如此迭代下去。(Algorithm of gradient Rosen projection method for solving constrained optimization problems)

循环冗余校验(CRC)的生成多项式为CRC-16: x16+x15+x2+1。(CRC-16: x16+x15+x2+1.)

a simple code for plot some kinds of geophysical data (such shot, CMP,... gathers).

blind watermarking in r , g,b planes using singular value decomposition in color images

cutting force calculation with coefficients

检测从键盘输入字符。用到了fiugre的 currentcharacter 属性，figure还有一个 currentkey 属性。这两个属性都能检测键盘输入，不过还是有不小区别，可以试一下。(Detection input from the keyboard characters. Use of the fiugre' s ' currentcharacter' property, figure there is a ' currentkey' property. These two properties can be detected keyboard input, but there are still no small difference, you can try.)

学习Matlab循环语句的好例子，适合初学者(err)
