I'm trying to construct a generalized transfer function for a fully connected neural net. Basically I need to solve these equations for Y[n] in terms of X[n] and the (n+1) x (n+1) array [a] and I can't figure out how to go about it. I make use of the 1-d arrays wout and win but they should drop out if solved correctly. Any suggestions? Thanks!!

wout[[i]] = win[[i]] g
Y[n] = Sum[wout[j] a[[j,N+1]],{j,1,N}]
win[i] = Sum[wout[j] a[[j,i]] + X[n] a[[N+1,i]],{j,1,N}]

Here follows the notebook code I think (I'm new to this whole mathematica thing):

\!\(wout\_\(\(\[LeftDoubleBracket]\)\(i\)\(\[RightDoubleBracket]\)\) =
win\_\(\(\[LeftDoubleBracket]\)\(i\)\(\[RightDoubleBracket]\)\)\ g\)

\!\(y[n]\ = \ \[Sum]\+\(j = 1\)\%N wout\_\(\(\[LeftDoubleBracket]\)\(j\)\(\
\[RightDoubleBracket]\)\)\ \[Alpha]\_\(\(\[LeftDoubleBracket]\)\(j, N + 1\)\(\
\[RightDoubleBracket]\)\)\)

\!\(win\_\(\(\[LeftDoubleBracket]\)\(i\)\(\[RightDoubleBracket]\)\) = \
\[Sum]\+\(j = 1\)\%N wout\_\(\(\[LeftDoubleBracket]\)\(j\)\(\
\[RightDoubleBracket]\)\)\ \[Alpha]\_\(\(\[LeftDoubleBracket]\)\(j, i\)\(\
\[RightDoubleBracket]\)\) +
X[n]*\ \[Alpha]\_\(\(\[LeftDoubleBracket]\)\(N + 1, i\)\(\
\[RightDoubleBracket]\)\)\)
