How to set the activation function in the output neuron in Matlab?

Question

Neural networks

I am making a simple neural network in matlab using Neural Net Fitting. In principle, everything turns out, but the output is not entirely satisfied. I'm training the network to produce results of 1 and -1, and the output is up to |10|. As I understand it, the output is an activation function that is not quite suitable for me and, in theory, a hyperbolic tangent is needed.
How can I force matlab to use hyperbolic tangent on the output neuron?
