this is matlab code for pprobality theory which is implemetatde in matab 7,6

Discrete Wavelet Transform using Daubechies Wavelet family for Stationery and non-stationery signal and test with ECG signal for compression as well. The Matlab code are very simple and detailed one to understand easily. Can change code and produce on for ones project as well. These code provided with outputs to understand what exactly we are doing and get known what DWT exactly is. I tried my best to provide simple code.

计算这一年已经逝去的天数（包括当天）。在平年中，它的取值范围为1到365，在闰年中，它的取值范围1到366。编写一个MATLAB程序，输入年，月，日，输出为对应的该天是当年的第几天。 闰年是这样规定的 1）.能被400整除的年为闰年 2）能被100整除但不能被400整除的年不为闰年 3）.能被4整除但不能被100整除年为闰年 4）.其余的年份不为闰年 (This year has calculated the number of days elapsed (including that day). In non-leap year, it ranges from 1 to 365 in a leap year, it s the range of 1 to 366. Write a MATLAB program, enter the year, month, day, corresponding to the output of the first year of the day is a few days. This leap is required 1) is divisible by 400 is a leap year 2) can be divisible by 100 but not divisible by 400 years is not a leap year 3) be divisible by 4 but not divisible by 100 is a leap year 4) the rest of the year is not leap year)

解线性方程组的一种迭代法，类似于共轭斜量法：预善共轭斜量法(Solution of linear equations of a iterative method, similar to conjugate oblique method: Pre-good conjugate oblique method)

Geometric Processing Package This package is on basic geometric processing, including common used algebraic/topological/graphical functions. Detailed documentation is available. It is planned to add more functions. Your suggestions are highly appreciated
