Re: [Scilab-users] Scilab 6.1 - Possible GUI Bug

[Chin Luh Tan]

sorry, the workaround does not work, the dockable value can only set during 
creation.

Hi, 



When trying to update guibuilder for Scilab 6.1, I notice that the figure menu 
is not able to be remove with "delmenu" when the "dockable" is set to "off".



How to reproduce:



Scenario 1: Menu "File" will not be removed

--> f1 = figure("dockable", "off") 

--> delmenu(f1.figure_id, gettext("File"));







Scenario 2: Menu "File" will be removed

-->f1 = figure("dockable", "on")

-->delmenu(f1.figure_id, gettext("File"));





Current workaround: 

-->f1 = figure("dockable", "on")

-->delmenu(f1.figure_id, gettext("File"));

-->f1.dockable = "off";



thanks.

[Scilab-users] Scilab 6.1.0 - MinGW

[Perrichon]

Hello

Many Thanks to Antoine for reintroducing MinGW tools in atom pack and plug,
after all discussions on email and phone last week-end, for compiling
palette in xcos with no errors and no warnings in c++.

Include files are ok now (.h)

Buider is ok. After other problems to discuss.

Re: [Scilab-users] several problems with xcos scilab 6.1.0

[Clément David]

Hello Pierre,

This change was introduced 6 months ago and is coherent to the default scope 
window for a beginner. This is the default settings that apply only to any new 
schema, for any saved Xcos diagram the previous value should be preserved; if 
not please report a bug.

Note: while investigating your issue, I tested the Xcos preferences and it 
failed to set up a default final simulation time; this is a bug reported at 
http://bugzilla.scilab.org/show_bug.cgi?id=16336

Hello,
Even if it is minor, apparently somebody has decided to define the time 
simulation to 30 s by default. Why ? I don't know
Before, it was 1.0E05 s and I stop the simulation with the END box in my main 
scheme. (to avoid user to go on this menu and choose another solver, at least). 
(choose is Newton for me , so the default one)
So I've hundred shemes to see

And this is not the first surprise.

Others tests don't work anymore

I can do tests to correct that, but it was not foreseen.

I still believe to go on with 6.1.0 but keep aware because not so clear with

Hello Heinz,

The macOS version is still in progress, we don't have any access to a macOS

So yes, we rely on the community (and especially Stephane) to ship a macOS

Note: this was also the case for Scilab 6.0.0 to 6.0.2.

Re: [Scilab-users] Line integrals

[Stéphane Mottelet]

Hello,

You can use intg, once you have forged the correct function of the 
parameter:


function  out=parabola(t)
out  =  [t/2;t^2];
endfunction

function  out=my_f(M)
out  =  2*M(1);
endfunction

function  out=line_int(a, b, curve, f)
function  out=fun(t, f, curve)
dcurve  =  imag(curve(t+%eps*%i))/%eps;
out  =  f(curve(t))*norm(dcurve)
 end
 out  =  intg(a,b,list(fun,f,curve))
endfunction

--> line_int(0,6,parabola,my_f)
 ans  =

   144.36474604669

The derivative of the curve w.r.t. the parameter is computed by using 
the complex step.

Hello all,

I am interested in doing line integrals on f(x,y) and f(x,y,z) for scalar
and vector calculations.

It is not an issue to do mathematically, but not so clear in Scilab how
variable substitution should work in this process. As I understand it, one
has to take the function and convert it to a parametric form in x,y,(z) in
order to reduce the integrand to a single variable (e.g. t) that can be
integrated simply.

Now, clearly it is not a problem to do the substitutions by hand and then
run the Scilab function (Integrate), but nice to simplify the procedure.

For the integral over a path (C) of f(x,y) ds, x and y have to be parametric
e.g. x(t) and y(t),
where ds = sqrt( (dx(t)/dt)^2 + (dy(t)/dt)^2 ) dt

Is there a simple route to solve line integrals in Scilab or building a
function to do this?
e.g. LineIntegral(expr,x(t),y(t),t,a,b), where x(t) and y(t) are the
parametric forms.

A very simple problem:

f(x,y) = 2*x with x(t)=t/2 and y(t)=t^2 for t=0 to 6
Substitution for x and y and solving the integral over t should result in
144.36 approx.

Any pointers would be useful. Could not see any reference in the mailing
list or help on this.

Thanks
Lester

I'm interested in integration of Scilab with Learning Management System

Maribor, Slovenia). 

 

I would be very glad if you could provide me examples of good praxis and
your experiences on this topics.
