hello!

i think that is no problem with my code, but this error is displayed : " Invalid operation: {6e+06} ./ {real affine}"

```
cvx_begin
variable U(m,n) binary
variables x(n) new_R(m,n) ;
maximise( sum( U ) )
subject to
for i=1:m
for j=1:n
Q-(Delay(m,1)+(alpha./new_R(i,j)))>= Value*(1-U(i,j)) % the error displays here
Emax-(Energy_Pr(m,1)+E_prop)>= Value*(1-U(i,j))
0 <= new_R(i,j) <= R_lb(i,j)
end
end
x(1) = x_start
x(n+1) = x_end
for j=1:n
norm(x(j+1)-x(j))= Vmax.taux
end
0 <= x_start <= 1000
0 <= x_end <= 1000
cvx_end
```
