can anyone send me the code for ANN which is applicable in this dataset?

Hi, you can use something like this:

I=xlsread('forneuralnetworkdataset.xls');
inputs=I(:,1:3)';
targets=I(:,4)';
net=feedforwardnet(10);
net=train(net,inputs,targets);

Thanks..But how can i test some sample data here? suppose I have temperature data,humidity data and pressure sample data.I want to see its corresponding weather class as per dataset.Then how can i write this code for ann?

You're welcome. You have the trained net. Simply use the net as a function:

out=net([28;89;993])

or
test_data=I(1:10,1:3)';
outs=net(test_data);

Note that the output of a default feed-forward network is not integer. You can use round, ceil, floor or fix function to round the output.

out=round(net([28;89;993]))

another question is that: I=xlsread('forneuralnetworkdataset.xlsx'); inputs=I(:,1:3)'; targets=I(:,4)'; net=feedforwardnet(10); net=train(net,inputs,targets); display(net); out=round(net([28;89;993])); display(out); In this above code I want to define a function and I want to pass this inputs as input arguments through this function.
