Follow-up Comment #1:

Thanks for your bug report. Confirmed here as well with your example. Also
worth quoting the example from the Matlab help for pcolor:


n = 6;
r = (0:n)'/n;
theta = pi*(-n:n)/n;
X = r*cos(theta);
Y = r*sin(theta);
C = r*cos(2*theta);
pcolor(X,Y,C)
axis equal tight


from

http://www.mathworks.com/help/matlab/ref/pcolor.html#example_2

This also yields the same error, which in the 4.0 development version looks
like:


error: ylim: axis limits must be increasing
error: called from
    __axis_limits__ at line 49 column 11
    ylim at line 44 column 7
    pcolor at line 117 column 9
