Thanks @Adrian Schad. The answer is correct and I am clear now.

@mvw. This result is reasonable, since if we take the partial derivative to the objective function, it is non-zero in general, which means the maximum value should be on the boundary. But I don't know whether it is hold in a general $n$, and the result is still all 0 except one $x_i=c$.

For the case $n=2$, it is shown that the result is always ${x_1=c,x_2=0}$ or ${x_1=0,x_2=c}$.

Thanks @mvw . Yes, I know that. For the ordinary linear fractional programming, I can follow the method from wiki and reformulate it to the LP. But I want to know whether it will be different for this special form. For example, the analytical solution can be obtained?

comment Inverse of a lower triangular Toeplitz matrix vs. the matrix size
Thanks @Pavel Jiranek. You are so nice. The inverse of the lower triangular Toeplitz matrix has the recursion form, exactly as what you have written. You can have a look at the link: ramanujan.math.trinity.edu/wtrench/research/papers/… But still, I need to think about how to solve it. Thanks.
