ICPC-camp2016年的课件，希望给acm-ICPC和信息学竞赛的大佬们带来帮助(ICPC-Camp courseware 2016, hoping to help the acm-ICPC and informatics competition bosses)

说明：  对IQ接收器最重要的两个参数,即I和Q两路分量之间的幅度一致性和相位正交性,可采 用如下办法计算:把I、Q 两路信号分别作FFT ,找出频域内信号的幅度,即可算得两路分量的幅度一 致性 把I、Q两路信号合成一个复数信号,作FFT ,对得到的频谱求镜像抑制比(即频域内的信号与信号镜像的幅度比) ,通过镜像抑制比和幅度一致性,可求出接收机的I和Q两路分量之间的相位正交性。(IQ receiver for the two most important parameters, namely I and Q components of two-way consistency between the amplitude and phase orthogonality may be adopted calculated using the following method: to I, Q 2 signals, respectively for FFT, to find a frequency domain signal amplitude, can be considered as two-way component caused by the range of 1 the I, Q 2 signals into one complex signal for FFT, the spectrum demand of the received image rejection ratio (ie, frequency domain signal and magnitude of the signal mirror ratio), through the image rejection ratio and extent of consistency, the receiver can be derived I and Q phase between the two-way component orthogonality.)

说明：  用ABAQUS扩展有限元方法模拟水里压裂的例子。(The program developed in Python language is mainly used to simulate the hydraulic fracture on ABAQUS platform. Plastic damage model is adopted for cement sheath.)

说明：  求解一些数学中最常见遇到的非线性最优化的模型，比如信号灯的优化配时问题求解等等。(conclusions)

给出了《IDL学习教程》中的若干function list。这里是与操作矩阵的相关函数。(Gives the " IDL Learning tutorial" in the number of function list. Here is the matrix of the correlation function and operation.)

说明：  关于导波的波动方程的源码，可以在matlab上直接使用(The source code of wave equation of guided wave can be directly used in MATLAB)
