function y = seqm(a, b, n) %SEQM Multiplicative sequence. % Y = SEQM(A, B, N) produces a row vector comprising N % logarithmically equally spaced numbers, starting at A ~= 0 % and finishing at B ~= 0. % If A*B < 0 and N > 2 then complex results are produced. % If N is omitted then 10 points are generated. if nargin == 2, n = 10; end if n <= 1 y = a; return end p = [0:n-2]/(n-1); r = (b/a).^p; y = [a*r, b];
