x = input';
t = target';
trainFcn = 'trainlm';
hiddenLayerSize = 10;
net = feedforwardnet(hiddenLayerSize,trainFcn);
net.divideParam.trainRatio = 70/100;
net.divideParam.valRatio = 15/100;
net.divideParam.testRatio = 15/100;
[net] = train(net,x,t);

Hello Ashish,
You can use ‘poslin’ as transfer function to the hidden layer which is same as applying ‘ReLU’ activation function.
You can use this code for using 'poslin'
net.layers{1}.transferFcn = 'poslin';
I hope this information helps and please reach out for any further issues.
