I have six input as natural frequencies while the output are the depth and location of damage in x and y direction . this means that the net has three outputs. when i trained the net the error is very high. how can I decrease the error. worth noting that I have 90 cases in total as input of the net.

x=Input;
t=Target;

% Create a Fitting Network

net = feedforwardnet(10);

% Train the Network

net = train(net,x,t);
view(net)
output = net(x);
perf = perform(net,t,output)
