SparseArrays map integers to Objects. Unlike a normal array of Objects, there can be gaps in the indices. It is intended to be more efficient than using a HashMap to map Integers to Objects.

计算函数的极值的另外一种方法 只是其中一种 以后会陆续上新的(Calculation of the extremal function of another kind of method is just one of the future will continue on a new)

用MATLAB实现神经网络BP算法。思路比较清晰，大家可以作为参考。(MATLAB neural network with BP algorithm to achieve. Ideas clearer, we can serve as a reference.)

解压之后.添加到matlab->file->set path里面,就可以直接运行InvGUI.输入具体的数值后,自动plot figure.(After decompression. Added to the matlab-> file-> set path inside, you can directly run InvGUI. Enter specific values, the auto-plot figure.)

Peak to Peak Analysis

介绍了matlab里常用的命令函数，便于查找使用。(The matlab command function, easy to find use.)

水文测量中的matlab仿真，包括自动行驶，采集数据，完整的仿真模型的搭建。(Hydrographic survey of matlab simulation, including automatic driving, data collection, build a complete simulation model.)

speckle noise in image processing

Model-based approach is widely adopted to develop embedded system to cope with the ever-increasing complexity of system design under relentless time-tomarket pressure.
