Derive a Neural Network Equation

I am trying to determine a way to get the outputs of my neural network equation to match the output from

sim(net,DataI)

Where DataI is just my input matrix.

I know the equation is y = repmat(b2,1,30) + LW*tansig(repmat(b1,1,30) + (IW*DataI));

but when I run this the outputs are different. I assume this is because I have not denormalized my data, but I am struggling to do that.

Best, John
