failure in reversed xdir or ydir axes

hi,

when invoking set to get reversed axes, the new axes labels overlap
with old ones and the axes does not get reversed effectively.

when running
plot(1:10)
set(gca(),"ydir","reverse")
or
plot(1:10)
set(axes,"ydir","reverse");
I get the following figure
http://www.nabble.com/file/p24288483/test.png test.png 

is that a known issue?
is there a simple fix?

thanks,
eric

Re: failure in reversed xdir or ydir axes

I click "post message" too fast

plot(1:10)
set(gca(),"ydir","reverse")
does work
while
plot(1:10)
set(axes,"ydir","reverse");
does not.

strcat in octave 3.2.0-mingw32

Using the binaries provided from sourceforge I encountered the following problem

> strcat('test ', 'space', ' in ' , ' between')
ans = testspace in between
octave-3.2.0.exe:44:U:\Daten
> strcat("test ", "space", " in " , " between")
ans = testspace in between
octave-3.2.0.exe:45:U:\Daten

Spaces at the end of strings are being cut away, this is obviously a different behaviour as in 3.0.3.... Is
this the intended behaviour or a bug ?

Thanks a lot

which() changed behavior between 3.0 and 3.2

Hi everyone,

Between Octave 3.0 and 3.2, the which() function has changed its
behaviour. More precisely, in 3.2, it no longer accepts script or
function filenames (with the ".m" extension) in argument.

Before:

octave3.0:1> x = which("betacdf.m")
x = /usr/share/octave/3.0.5/m/statistics/distributions/betacdf.m

After:

octave3.2:1> x = which("betacdf.m")
x = 

Is this a bug or is it the new expected behaviour?

Note that in MATLAB, which() accepts filenames, like in Octave 3.0.

Best,

discrepancy between 'zeros' and 'eye' in octave-3.0.5

Hello,

'help zeros' among other things says:

"The arguments are handled the same as the arguments for `eye'."

In practice:

"
octave:39> zeros([0 1 2])
ans = [](0x1x2)
octave:40> eye([0 1 2])
error: eye (A): use eye (size (A)) instead
",

i.e. there is an error message in case of 'eye' and no error message in 
case 'zeros', so I'd say it's not the same way.

Thanks,
  Sergei.

"All Zero guesses not acceptable" in 'optim-1.0.4/leasqr.m'

Hello,

I think "All Zero guesses not acceptable" in 'optim-1.0.4/leasqr.m' is a 
wrong limitation.

The guesses, I guess, are related to the parameters to be calculated by the
function.

Suppose we have the following function:

y = p * x

where 'y', 'p', 'x' are scalars.

Suppose there are two observed values according to the following table:

x y
1 1
2 2
.

So, if I guess p = 1, it's the correct solution.

Suppose I rewrite the function differently:

y = (1 + p) * x

, and observed values are the same, as well as observation points.
