这是用MATLAB编写的静态图片压缩程序中的基于灰度解压部分

发射部分采用锁相环式频率合成器技术， MC145152和MC12022芯片组成锁相环，将载波频率精确锁定在35MHz，输出载波的稳定度达到4×10-5，准确度达到3×10-5，由变容二极管V149和集成压控振荡器芯片MC1648实现对载波的调频调制；末级功放选用三极管2SC1970，使其工作在丙类放大状态，提高了放大器的效率，输出功率达到设计要求。-Part of the launch phase-locked loop frequency synthesizer using technology, MC145152 and MC12022 PLL chips to lock in the exact carrier frequency 35MHz, the output carrier to achieve the stability of 4 × 10-5, reaching the accuracy of 3 × 10-5 by the varactor diode V149 and integration to achieve MC1648 chip VCO FM modulation on the carrier selection transistor amplifier at the end of class 2SC1970, to work in the C state to enlarge and improve the efficiency of the amplifier output power to meet the design requirements.

玩双色球的过程中，无论把33个红色备选号码球怎样划分区间，总会时不时地有某个区间不出号（即所谓的断号或断档）。如果我们在选号时，能够把不出号的区间排除在我们选号范围之外，就会大大缩小选号的范围，增加中奖的机会。 -Loans play the process, regardless of the number 33 red balls what division options range from time to time there will always see a certain number range (the so-called off or断档).选号If we can not issue the interval excluded from the scope of our选号, it will greatly narrow the scope of选号to increase the chance of winning.

编写程序计算三门课的平均成绩，要求应用程序分别用Java语言三种不同的循环语句实现，每门课的成绩用Math类的random()方法随机产生（random()产生的数值在0和1之间），成绩范围为40~100。 提示:自定义一个类，该类实现一个返回随机数的函数。在main函数里测试时直接调用该类的获取随机数方法。 获得随机数相关的类为:java.lang.Math 需要时可引入该类即:import java.lang.Math -Write a program grade point average calculation of three lessons to require the application were used Java language in three different loop realization of the achievements of each course with the Math class, random () method of randomly generated (random () produces values between 0 and between 1), results range from 40 ~ 100. Tip: Customize a class that implements a function to return random numbers. In the main function, where the test is called the class to obtain a direct method of random numbers. Obtain a random number associated category: java.lang.Math necessary for the introduction of the class that is: import java.lang.Math

此程序实现采用了两个算法；雅克比迭代算法和高斯塞得迭代算法，通过这两个算法可以计算任何其次线性方程组。在应用者两个算法之前，还进行判断所代的其次线性方程组是否能用该方法求解
