I am trying to find the sensitivity of a feedforward neural network. For example, to find the sensitivity of the following feedforwardnet
[x , t] = house_dataset;
net = feedforwardnet(10);
net = train(net, x, t);
I used the formula
s = b2 + Lw * tanh(b1 + Iw * x)
But it has the following error
Error using + Matrix dimensions must agree.
I am trying to find another solution. Please Help me on how to find sensitivity of a neural network Feedforward net.

Sensitivity to what?
The above equation has the right form however, you have to make the dimensions of the biases compatible using the function repmat.
Use the command
whos
to make sure dimensions are compatible.
Hope this helps.

You forgot to take into account that the input is 13 dimensional
