Hi Jens,
grep does something like what you want.
-->[r,w]=grep(Ms,M);
-->matrix(w,size(Ms))
ans =
12.4.
2. 12.
6. 7.
Not sure why grep produces a vector when searching for a matrix, but it
seems that way.
HTH,
Mike.

Hi Paul,
Would Scilab's try-catch block do what you want? For example:
for i=1:10;
try;
disp(1/(i-5));
catch;
disp("err");
end;
end
won't crash when it gets to the divide by zero.
This is the more structured way, but you can use execstr with errcatch to
do the same thing.
Hi Paul,
Usually the envelope is calculated via the magnitude of the Hilbert
transform. Check out Hilbert in the help. As usual there are some
caveats, but often this is close enough without further work.
HTH,
Mike.

Hi Pascal,
Not sure about DotNet, but some time ago I reported a problem with this API
for C (not c#) because the third parameter is specified as int*, but is in
fact int. If your compiler is fussy, this could be the problem. Try
(NULL, NULL, 0). I found that fixed it for me.
Hope that helps,
Hi,
vet = 1:4;
disp (vet(3));
will do almost the same thing. But note that Scilab indices start at 1, not
zero, so vet does not include the element vet[0] = 0;
HTH,
Mike.

Hi,
If you want to remove outliers from a data set, you can use the modified
Thompson Tau method. Basically tau provides a limit based on mean and
standard deviation so that values outside (mean +/- n * std dev) are
rejected. The method is unfortunately iterative, but it works well. You
can rem
Hi Eduardo,
Sometimes I have had problems like this due to line termination characters.
It's possible if a file gets moved from Linux to Windows and back again, it
can get unexpected CR or LF characters. Sometimes these are read as a
garbage line. I would take a look at your text file with a hex
Hi,
I have been using the Levenberg-Marquardt solver (lsqrsolve), but would like
to look at ways to adjust it to better suit my particular problem. Does
anyone know if the souce code for this is available anywhere and if it is in
fact open source?
Thanks,
Mike.

Hi Larissa,
I'm no expert on this, but have you tried changing the data_bounds for the
figure's children independently? I think if you just set the colorbar limits
with colorbar(a,b), that only changes the legend on the bar itself.
Try f=gcf(); then look at f.children(1),data_bounds or
f.chil
Hi,
You are asking a question which in general has no answer. There are an
infinite number of models which can fit your data. You need to find some
possible candidate model forms based on physical properties and then try
fitting to them. You are probably looking for a fit which leaves residu
Hi,
I tried Sci2C once (a while ago now), but I found it had too many
limitations. For me the lack of support for hypermatrices was enough to
make it not usable. There is (I think) an example of Sci2C that shows how
it works, but I don't remember where - sorry.
One other way to solve your probl
Hi,
I think this is just a question of scaling. There is no "correct" scaling
for the FFT - just some different conventions. This is explained here
(http://www.mathworks.co.uk/matlabcentral/answers/15770-scaling-the-fft-and-
the-ifft).
The "correct" answer with Scilab would be exactly 100 (N/2)
I have just checked on Scilab 5.3.2 and found this works on that version, so
it looks like a bug.
Mike.

Hi,
I am trying to use the Nelder Mead optimisation functions to fit a
biological model to some experimental data. I am using Scilab 5.4.0 on Win
XP.
The search halts with the error:

Invalid index.

You could of course "define constants" in Scilab. This is what I usually do:
[NONE, CONTINUOUS, DISCRETE, FFT] = (1, 2, 3, 4);
OK - not perfect, but it makes code more readable.
HTH,
Mike.

Hi Paul,
Assuming the relationship between x, y and T is approximately linear, then
you can just match the points on the curves pairwise and interpolate between
the pairs using interpln. If your target temperature T is such that T = aT1
+ (1-a)T2, then it will produce a point at abscissa x = ax1
