Hello,
Replacing the squared L2 norm by the L1 norm in the linear regression
gives a good robustness to outliers (cf. Donoho and al. papers). The

iteratively reweighting the classical L2 method (IRLS method), or by
writing an equi

your costfunction has to provide f and its gradient :

endfunction
x0=[100,100]';

BTY, I am worried about the Scilab 6.0 timing (3.3228213 seconds) of

I have a very general and naive question concerning leastsq: what am I

Is there a way to link it to the confidence interval for each

Not really,
Why not use median filtering with a small window ?

Hello,
The last time I had used a median filter, it was to locate peaks in a
frequency DSP. The idea was to substract the median-filtered spectrum to
the original one, and treshold the difference. This was enough to locate
the peaks. Maybe you could use the same idea there.

It seems to be the normal behavior, as int() and floor() behave the same
for positive numbers (and 1.45 cannot be stored exactly with IEEE 754)

Hello,
1-parallel_run is designed to cope with input-output data organized in
columns
2-you have to precise the size of the output of yout fct() function.

Hello,
IMHO parallel_run is very unstable and should be considered as an
experimental feature. I never managed to make it work with multiple
arguments. The workaround is the following :
function U=fct(i)
U1 = R1(i) * i1(i);
U2 = R2(i) * i2(i);
U = [U1 U2]';
endfunction
n = 1000;
The price :-D

As parallel_run is using child Scilab processes, the std output of all children

Hello,
Cascaded frequency modulation gives nices sounds. For example signals like
sin((w0+a1*sin(w1*t))*t)
w1 itself can also be modulated, and so on. This kind of synthesis was
used by the famous Yamaha DX-7 and gave typical sounds (bass guitar,
bells, ...)
