采用matlab编写，对图像椒盐噪声与周期性噪声的进行滤除(Using matlab, image noise and periodic noise salt and pepper to filter out)

说明：  基于MATLAB/SIMULINK的PMSM仿真与实现(PMSM)

采用DSP Builder设计的DDS信号发生器(The DDS signal generator using DSP BUILDER design)

基于MATLAB软件下的QPSK 调制解调(MATLAB-based software under the QPSK modulation and demodulation)

说明：   格式：x=masor(A,b,omega,x0,ep,N) A为系数矩阵，b为右端向量， 用途：用复辛普生形公式求积分。( Format: x = masor (A, b, omega, x0, ep, N) A as the coefficient matrix, b for the right-hand side vector, Uses: The complex shape Simpson quadrature formula.)

Fminsearch不承认的约束限制。 不过简单的转换方法存在 转换成一个绑定的约束问题 无约束问题。 Fminsearchbnd用于酷似fminsearch， 除了边界应用到变量。 应用于国内的界限，利用 改造中的变量。 （二次型 单式，双罪恶界（十）。） 具有包容性的不平等的界限，它承认 边界值本身，但不准 在所有函数之外的范围评估。 请注意，fminsearchbnd允许用户准确地固定在某个给定值通过设置一个变量的确切范围相同的值。(Fminsearch does not admit bound constraints. However simple transformation methods exist to convert a bound constrained problem into an unconstrained problem. Fminsearchbnd is used exactly like fminsearch, except that bounds are applied to the variables. The bounds are applied internally, using a transformation of the variables. (Quadratic for single bounds, sin(x) for dual bounds.) The bounds are inclusive inequalities, which admit the boundary values themselves, but will not permit ANY function evaluations outside the bounds. Note that fminsearchbnd allows the user to exactly fix a variable at some given value, by setting both bounds to the exact same value.)

本文介绍MATLAB在概率统计中的若干命令和使用格式，希望大家多多支持啊!(in probability and statistics of a number of orders and the use of the format, we hope the generous support ah!)

两自由度比例前馈simulink模型，测四轮转向的质心侧偏角和横摆角速度(Two degrees of freedom ratio feedforward simulink model, measuring four-wheel steering center of mass of side-slip Angle and yawing angular velocity )
