写一段基于港口吞吐量预测的LSTMmatlab算法代码

设置网络参数：
net = network;
net.numInputs = 1;
net.numLayers = 3;
net.inputConnect(1,1) = 1;
net.layerConnect = [0 1 0; 0 0 1];
net.outputConnect = [0 0 1];
net.inputs = {'input'};
net.layers = {'lstmLayer' 'fullyConnectedLayer' 'regressionLayer'};
net.biasConnect = [1; 1; 0];
net.layerWeights = {zeros(6,1),zeros(1,6),0};
net.layerDelays = {[0], [0], [0]};
net.outputMode = 'regression';
net.performFcn = 'mse';
net.plotFcns = {'plotperform','plottrainstate','ploterrhist','plotregression'}; 设置网络参数：
net.divideFcn = 'dividerand';
net.divideParam.trainRatio = 70/100;
net.divideParam.valRatio = 15/100;
net.divideParam.testRatio = 15/100; 训练网络：
[net,tr] = train(net,inputs,targets); 预测：
outputs = net(inputs);
errors = gsubtract(targets,outputs);
performance = perform(net,targets,outputs);
