function y = logspace10(d1, d2, n)
%LOGSPACE10 Logarithmically spaced vector.
%
%   LOGSPACE10(d1, d2) generates a row vector of 100 logarithmically equally
%   spaced points between 10^d1 and 10^d2.
%
%   LOGSPACE10(d1, d2, N) generates N points.
%
%   The main difference between LOGSPACE10 and LOGSPACE (MATLAB) is that
%   LOGSPACE10 does not treat D2 = PI as special.
