DIGITAL IMAGE WATER MARKING USING DCT

说明：  MATLAB示例代码 从2004年11月起，《MATLAB及在电子信息课程中的应用》的下载程序dsk01改为dsk02。两者只有微小的差别。主要的修改是： 1． 所有的生成图形都由灰色改成白色，以便与书籍上的图相同。 2． 删去了几个无用的程序； 3． 加了了几个程序（如q48a和q48b），以便和书上的章节演示内容相符。(MATLAB sample code from November 2004 onwards, "MATLAB and electronic information in the curriculum of" download dsk01 dsk02 changed. Taken only a very small difference. The major changes are : 1. All graphics generating replaced by gray and white, with the books to the same map. 2. By deleting a few useless procedures; 3. The increase in the number of procedures (such as q48a and q48b), and to book chapters on the demonstration line content.)

计算了贝塞尔函数的一阶导数的零点。 更新BessDerivZerosBisect.m这些变化： 1。允许对m= 0 2。允许用户指定特定的m和k值理想。 3。允许公差输入参数 4。使用一个表的查找能为m和k的小值接近初始化 5。添加错误检查 6。计算衍生w.r.t.以X而不是w.r.t.米（虽然老方法的工作也。）(Calculates the zeros of the first derivatives of Bessel function. Updates BessDerivZerosBisect.m with these changes: 1. Allows for m = 0 2. Allow the user to specify the particular m and k values desired. 3. Allows for a tolerance input parameter 4. Uses a table look-up to get closer initializations for small values of m and k. 5. Adds error checking 6. Computes the derivative w.r.t. to x rather than w.r.t. m (although the old method works, too.))

用牛顿法计算简单电力系统潮流，可以计算任意节点的潮流。自动输出中间的相关结果，并且有清晰可以操作的界面(Newton s method with a simple power flow)

这是一个节点潮流计算算法程序，有兴趣的朋友可以看看(This is a node flow calculation algorithm, interested friends can see)
