Hi!
diffcode 1.1.1-1: I once filed the bug 13431 and I see the status is
RESOLVED MOVED. But the bug persists in the ATOMS version under 5.5.1
Linux 64 bits. The fix is very easy but I need it to be installed OK for
my students instead of instructing them to apply the fix by themselves.
The fix is to modify the file
SCILABHOME/share/scilab/contrib/diffcode/1.1.1-1/macros/diffcode_CDcost.sci
replacing
f=fun(x)
by
f=fun(x,varargin(:)) // JPD ajouté le varargin
The following example crashes without the fix.
Thanks,
JPD
function [val]= fexlum(x,varargin);
val=0;
o=varargin(1);
p=varargin(2);
val = sqrt((p(1)-x)^2 + (p(2)-x^2)^2);
val = val + sqrt((o(1)-x)^2 + (o(2)-x^2)^2);
endfunction
x0=2;
oo = [2,1];
pp = [1,-1];
[fopt,xopt,gopt]=optim(list(diffcode_CDcost,...
fexlum,oo,pp),x0,'nd')
x=-1:0.1:1;
plot2d(x,x^2)
plot2d([oo(1),xopt],[oo(2),xopt^2])
plot2d([pp(1),xopt],[pp(2),xopt^2])
