有限元计算软件Nastran 运算出错时的所有错误列表，从标号1到22107.7。(FEM calculation error list of all software Nastran Error from grade 1 to 22,107.7.)

在uVision环境下用C编程，用离散傅里叶变换可以计算出频率的值(In uVision environment using C programming, using discrete Fourier transform frequency value can be calculated)

主要是交通行业的时空矩阵的3维热力图表达方式，不同检测器与不同时间段的流量作为颜色的第三位导入，热力图调整颜色表达更清晰(mianly used for transportation engineering. It can plot the three dimension of the real traffic situation, including different temporal and spatial. the code also can modify the parameter of the colorbar.)

递归神经网络-实时学习训练算法代码，亲测可用，简洁无误，容易上手。( Recursive neural network- real-time learning training algorithm code, pro-test available, simple and correct, easy to use.)

说明：  ADAM （Adaptive Moment Estimation）是另外一种自适应学习率算法，它结合动量梯度 下降法，在不同参数方向上采用不同学习率，保留前几次迭代的梯度，能够很好 的适应于稀疏数据。(ADAM (Adaptive Moment Estimation) is another adaptive learning rate algorithm, which combines momentum gradient. The descent method, which uses different learning rates in different parameter directions and retains the gradients of previous iterations, is very good. It is suitable for sparse data.)
