Hi, The status of Hydra job ‘gnu:octave-default:build.x86_64-linux’ has changed from "Failed" to "Failed". For details, see http://hydra.nixos.org/build/23221584 This may be due to 7 commits by Casey Ransom <casey.ransom <at> lookout.com>, John W. Eaton <jwe <at> octave.org>, Rik <rik <at> octave.org> or Vladimír Čunát <vcunat <at> gmail.com>. Go forth and fix it.

Anyone have any ideas on this one?  According to the log it looks like run-octave is failing to execute during 'make check'

make -C test check make[1]: Entering directory `/tmp/nix-build-octave.drv-0/octave-4.1.0+/test' Makefile:2789: warning: overriding recipe for target `check' Makefile:2172: warning: ignoring old recipe for target `check' building check ../run-octave --norc --silent --no-history ./fntests.m . building of ‘/nix/store/z6m6s0mjgiyqih2gmy7yzvr4bp2as3zd-octave.drv’ timed out after 7200 seconds of silence Could this be the result of changes to the gui-wizard? --Rik

FYI:gcc-4.9.3

gcc-4.9.3 is released on June 28.
On cygwin ML, there is a request to update version of gcc from 4.9.2 to 4.9.3.

Is the mxe-octave related?

fmincon wrapping nonlin_min

Hi Olaf,

I need some help in wrapping fmincon to nonlin_min:

- User supplied gradient of nonlinear constraints.
Consider the example:

objective_function =  <at>  (p) p(1)^2 + p(2)^2;
 pin = [-2; 5];
 constraint_function =  <at>  (p) p(1)^2 + 1 - p(2);
 gradc =  <at> (p) [2*p(1);-1];
 [p, objf, cvg, outp] = nonlin_min (objective_function, pin, optimset
("equc", {constraint_function, gradc}))

It gives the following error:
error: function handle type invalid as index value

What is the right way pass gradc to nonlin_min?

- Another simple example:

f =  <at> (x) -x(1) * x(2) * x(3);
S = [1  -1;   2  -2;   2  -2]
b = [0;72];
x0 = [10;10;10];
[x,fval] = nonlin_min( f, x0, optimset ("inequc",{S,b}) )

Gives an error with lm_feasible
error: __lm_feasible__: operator -: nonconformant arguments (op1 is
3x1, op2 is 3x0)
__lm_feasible__.m at line 208, column 11

but it works fine with octave_sqp.

- Output Gradient and Hessian at the solution as in Matlab.

- Output Lambda as a structure: changing backend to octave_sqp when
this output is requested? but the ordering issue again comes down to
the lambda returned from qp.

My code for fmincon:

Kind Regards,
Asma.

gnuplot graphics toolkit bugs

Is the 4.0 moratorium over with?  There's a backlog of gnuplot graphics 
toolkit bugs/patches that should be addressed, and I think those users 
who like the gnuplot toolkit will miss having more flexible gnuplot 
options.  Most of the following have an associated changeset, but not 
sure how out of date they are (I can update them in next couple weeks if 
need be):

https://savannah.gnu.org/bugs/?38914
bug #38914: Gnuplot axis reverse is not working with gnuplot 5

https://savannah.gnu.org/bugs/?44932
bug #44932: Add support for gnuplot xterm terminal type

https://savannah.gnu.org/bugs/?44861#comment4
bug #44861: Image display in a 3D view

https://savannah.gnu.org/bugs/?44187
bug #44187: Bugs and modifications in print() with gnuplot graphics toolkit

https://savannah.gnu.org/bugs/?34523
bug #34523: surf() with gnuplot does not handle FaceColor correctly

https://savannah.gnu.org/bugs/?45139
bug #45139: gnuplot gtk: Patch demo example 7 does not have a jet() gradient
[This one I've held off because it requires some fairly sizeable changes in
gnuplot, including hidden 3D surface (removal).]

https://savannah.gnu.org/bugs/?44978
bug #44978: gnuplot toolkit fails to recognize problems with older 
gnuplot versions

https://savannah.gnu.org/patch/?func=detailitem&item_id=8203
patch #8203: Add -ddumb device to print.

https://savannah.gnu.org/bugs/?43552
bug #43552: linewidth and markersize reduced when printing compared to 
the gnuplot window

https://savannah.gnu.org/bugs/?func=detailitem&item_id=43907
bug #43907: OpenGL render code called even when gnuplot is graphics_toolkit
