光学仿真
说明： 设计半径为1mm的平面波经凸面曲率半径为25mm，中心厚度3mm的平凸透镜。用matlab仿真平面波在透镜几何焦平面上的聚焦光斑强度分布，计算光斑半径。并与理论光斑半径值进行对比，得出误差大小。（方法：采用波动理论，利用基尔霍夫—菲涅尔衍射积分公式。）(Design a plano-convex lens with a plane wave radius of 1 mm and a convex curvature radius of 25 mm and a center thickness of 3 mm. Matlab simulates the intensity distribution of the focused spot on the geometric focal plane of the lens with a plane wave, and calculates the spot radius. The error is compared with the theoretical beam spot radius.)

LSTM时间预测matlab代码
说明： lstm时间预测matlab代码。程序说明：DATA.mat 是一行时序值，
numdely 是用前numdely个点预测当前点，cell_num是隐含层的数目，cost_gate 是误差的阈值。直接在命令行输入RunLstm(numdely,cell_num,cost_gate)即可(This is the matlab code of LSTM time prediction. Program description: data.mat is a row of sequential values,, Numtell is to use the previous numtell points to predict the current point. Cell num is the number of hidden layers, and cost gate is the threshold of error. Enter runlstm numtell from the command line)
