Abstract In this paper, for a given set of real numbers such as $\sigma$ with only one positive number and zero summation, we find a distance matrix in which the given set $\sigma$ is its spectrum.
Finally,  we solve special cases of the inverse eigenvalue problem in which the matrix solution is a regular spherical distance matrix.
