Dimenion matrix gaussian radial function

Hello!!!!

how can I determinate the dimesion of the gaussain radial basis function in neural network when I try to applicate it on 4-DOF robotic arm??????

please I get this error on my program I don't know how to solve it:

Matrix dimensions must agree.

Error in unconstrained_KUKA_LBR (line 151)

S(i,1)=exp(-(Z(:,1)-Mu(:,i))'*(Z(:,1)-Mu(:,i))/variance);

Error in odearguments (line 90)

f0 = feval(ode,t0,y0,args{:}); % ODE15I sets args{1} to yp0.

Error in ode23 (line 114)

odearguments(FcnHandlesUsed, solver_name, ode, tspan, y0, options, varargin);

Error in Rununc (line 6)

[T,Y]=ode23('unconstrained_KUKA_LBR',t,x0);

This is my code
