Why is there a error message that says the numbers of input signals and networks inputs do not match?

14 views (last 30 days)
Below is a copy of my code and I couldn't manage to get it to configure properly because of the error message. When I run the code it says the numbers of input signals and networks inputs do not match. Some help much appreciated.
x = linspace(0,10,100);
z1 = [0.001 1 1.5 2 2.335 2.5 3 4 5 6 7 8 10];
invx = 1./x;
invz = 1./z1;
z = [z1;invz];
t = Mg(z1,invz);
net = feedforwardnet;
net.numinputs = 2;
net.numLayers = 1;
net.inputConnect = [1 1];
net = configure(net,z,t);
NOTE: Mg is a separate file of some function of R and inverse R.
Thank you Greg for the comment, I apologise for the error, below is a copy of Mg.m file.
function value = Mg(r,inverseR)
B = 3.82045;
b = 1.31633;
beta = 2.17316;
C = -0.19641;
Rc = 2.30156;
c = 0.61347;
gamma = 1.79411;
D = 0.00082;
Rd = 1.83495;
d = 0.74887;
delta = 1.86846;
value = (-2.*inverseR).*(tanh(r)) + B.*(exp(-(r./b).^beta)) + C.*(exp(-(abs((r-Rc)./c).^gamma))) + D.*(exp(-(abs((r-Rd)./d).^delta)));
end

Note that typically, all you have to define is the input and target.
Use of CONFIGURE is UNNECESSARY
It can be as simple as this
See HELP FITNET
[ x, t ] = simplefit_dataset;
[ net tr y e ] = train( fitnet ,x, t );
MSE = mse(e)
