I have trained my ANN using the bodyfat_dataset. After that I created a new input matrix with 13 features and 18cases. However I didn't find any example of how to predict the new output.
load fatPred.csv
Xpred = fatPred;
predict(net,Xpred)
When i use this function, it says this only work with single inputs. I then tried
sim(net.Xpred)
The sim function gives me some outputs but I'm not sure if they are correct. Can someone help me understand how to use the predict function for my case please? Thank you.

What you are doing with sim is correct. With a shallow neural network, you can perform inference in two ways:
Y = sim(net, X);
or
Y = net(X);
