Scale an image and add a value

this is a lte project that simulate the senario with lte-sim.in this project the performance of handover in lte system is evaluated.

小波包分析提取振动信号中的特征频率，一个很有用的程序，数值分析的EULER法。( Wavelet packet analysis to extract vibration signal characteristic frequency, A very useful program, EULER numerical analysis method.)

The sparsity of signals and images in a certain trans-form domain or dictionary has been exploited in many applications in signal and image processing. Analytical sparsifying transforms such as Wavelets and DCT have been widely used in compression standards. Recently, synthesis sparsifying dictionaries that are di-rectly adapted to the data have become popular especially in appli-cations such as image denoising, inpainting, and medical image re-construction.

多径衰落信道matlab仿真程序，有说明(multi-path flat fading)

实现dft基本功能。对频率分辨率有特殊说明，希望对您有帮助。(The realization of the basic functions of dft. Frequency resolution of special note, I hope for your help.)

大变形测量数字图像的种子点匹配方法（图像匹配)(Large Deformation Measurement of digital image matching method of seed points (matching))

说明：  电力系统的牛顿-拉夫逊法潮流计算。 基本步骤： （1）形成节点导纳矩阵 （2）将各节点电压设初值U， （3）将节点初值代入相关求式，求出修正方程式的常数项向量 （4）将节点电压初值代入求式，求出雅可比矩阵元素 （5）求解修正方程，求修正向量 （6）求取节点电压的新值 （7）检查是否收敛，如不收敛，则以各节点电压的新值作为初值自第3步重新开始进行狭义次迭代，否则转入下一步 （8）计算支路功率分布，PV节点无功功率和平衡节点柱入功率。(Power system of Newton- rafer Johnson flow calculation method-matlab)

计算声音的旋律，利用了听觉模型和相关函数。(Calculation of the melody of the voice)

最近做的作业，费了好大劲才搞出来的MUSIC算法代码，需要的人可以借鉴额(Do the job, took great perspicacity to engage in the MUSIC algorithm code, people in need can learn from the amount of)
