前方交会摄影测量matlab编码。其中xy是相片坐标，XYZ是地理坐标，ms是摄影比例尺(Forward rendezvous photogrammetry matlab coding)

本人整理的vb6.0 常用API函数、内部函数、指令、经典例子的文档，希望大家喜欢。(I am finishing vb6.0 common API functions, internal functions, commands, classic example of a document, I hope you like it.)

说明：  The 3rd operational mode for the LDC

说明：  人工智能学习入门书籍，经典西瓜书，对于基础的人工智能学习有较为有用的帮助。(The introduction book of artificial intelligence learning, classic watermelon book, has more useful help for the basic artificial intelligence learning.)

通过Labview调用外部dll（其他语言编写的动态链接库），实现基于LV的数据采集。(Labview call through an external dll (written in languages other dynamic-link library), the LV-based data collection.)

基于模型预测的永磁同步电机直接转矩控制，通过建立其预测模型，并且评估每个电压矢量作用所产生的结果，选择最优的电压矢量并得到其PWM信号施加到变压器上以此来控制PMSM的转矩。该文件包含仿真文件，但是不包含模型预测控制的程序，程序获取方式在文件中(Direct torque control of permanent magnet synchronous motor based on model predictive control is established. By establishing its prediction model and evaluating the result of each voltage vector action, we select the optimal voltage vector and get the PWM signal to be applied to the transformer to control the torque of PMSM.)

说明：  用于计算高超音速飞行器再入大气层的表面烧蚀热化学反应计算(CALCULATION OF THERMOCHEMICAL REACTION OF SURFACE ABRACTION FOR REENTRY OF HIGH SUPERSONIC VEHICLES)

Rockchip 资料 ,spec ,就是常用的数据表格.(Rockchip information, spec, is commonly used in data tables.)

说明：  本书介绍基于FPGA实现数字信号处理的原理与方法，作为Xilinx公司相关课程的培训教材(The FPGA implementation of DSP principle & method.)
