Details:

Line 74:75 (at least in my installation) in qqplot.m states:


74:  elseif (ischar (dist) && (exist (invname = [dist "inv"])
75:                               || exist (invname = [dist "%s_inv"])))


which should, as I understand it, be


74:  elseif (ischar (dist) && (exist (invname = [dist "inv"])
75:                              || exist (invname = [dist "_inv"])))


With the code today, qqplot fails on distributions where the inverse is named
"dist_inv" - it works when the inverse function is named "distinv".

Thus, qqplot (x, "unif") works, whereas qqplot(x, "laplace") fails.
