The problem is in 'escalexy.m', in line 86
ticOffset=(iTic-nShortTics)*signOfDelta*deltaLabel/5;
values for the relevant call:
ticOffset = 3.0000e+04
iTic = 5
nShortTics = 3.9250
signOfDelta = 1
deltaLabel = 2000000
However:
debug> ticOffset - 30000
ans = 6.9122e-11
This non-zero values triggers a 'wrong' value for 'firstTicValue'.
Writing the statement as
signOfDelta*deltaLabel/5 * iTic - ...
signOfDelta*deltaLabel/5 * nShortTics
fixes it for me. However, I'm not sure whether this kind of 'fix' is
good: it makes the code more difficult to understand and might just
trigger problems in other cases (for example, if both numbers are
small).
Any ideas?
