帮我用matlab写一下LSTM做预测的4个输入节点1个输出节点代码

使用 Matlab 写出预测用 LSTM 的 4 个输入节点 1 个输出节点的代码可以这样：% 定义 LSTM 网络的结构
numFeatures = 4;
numResponses = 1;
numHiddenUnits = 200;layers = [ ...
sequenceInputLayer(numFeatures)
lstmLayer(numHiddenUnits)
fullyConnectedLayer(numResponses)
regressionLayer];% 设置训练参数
options = trainingOptions('adam', ...
'MaxEpochs',250, ...
'GradientThreshold',1, ...
'InitialLearnRate',0.005, ...
'LearnRateSchedule','piecewise', ...
'LearnRateDropPeriod',125, ...
'LearnRateDropFactor',0.2, ...
'Verbose',0, ...
'Plots','training-progress');% 训练 LSTM 网络
net = trainNetwork(xTrain,yTrain,layers,options);
