I need a complex version of the complementary error function erfc.
SCILAB currently supports only erfc for real numbers (contrary to
MATLAB).
Does anyone have already some code?

I am having particular trouble with format strings as I haven't seen
Fortran in 30 years and never did anything in C. Also don't see how to
neatly detect end of file.
sample code

here is another problem: In order to estimate the optimal value for a
recurrence plot analysis of some time series, I have to identify that
part of a curve (of remotely sigmoidal form) which best fits to a linear
equation: the linear scaling region. i.e. not necessarily a linear

I am new to SciLab.  I'd like to use plot3d to plot multiple surfaces.
I just do not get the documentation on how to do that (You can draw
multiple plots by replacing  xf  ,  yf   and  zf   by multiple matrices
assembled by rows as  [xf1 xf2 ...]  ,  [yf1 yf2 ...]   and  [zf1 zf2

I wanted to have a 3D plot of a survey. The thing is that I do not
always have a perfectly rectangular array. I wanted to do a meshgrid
but there are too many points.
I wondered if it was possible to have something like plot(x,y,z) with z

MATLAB can read rectangular array of data using
load name.ext
Is there any similar function available in scilab?
Thabnks,

I need to calculate an integral like the follwing with scilab and I
dont know how, can someone help me:
$\int_0 ^10 \frac{\int_0^s cos(xy)x^10 dx}{1+\int_0^s sen(xy)x^20 dx}
dy$

Is possible call a DLL from Scilab ?

I know it is a recurrent topics, but I have not find yet useful
informations. I'd like to create a C++ program managing the user GUI,
and calling some SCILAB routines.
Before proceding with this project I tried to first compile one of the

Given a list of data files in my working directory, file_names, I wish
to load the data, and name the variable via the basename of the file.
e.g something like
  fid = file('open',file_names(i),'unknown');

The README_Windows.txt for windows contains the following lines:
   1 - To compile with Visual C++ .NET 2003 & Intel Fortran 9.0,
       see Readme_visual.txt
   2 - To compile with  Visual C++ 6.0

Hi folks. Does anyone know if scilab implements a function to list all
subdirectories relative to a given path? I began writing my own, but my
programming skills are less than adequate. Ultimately, in the end, I
wish to have a process that can take as input the working directory,

I'm new to Scilab, and only used matlab sparingly. I've built an
electrocardiogram, and would like to use scilab to analyze, process,
and store the data. It seems that scilab is fast enough; but I wanted
to make sure it can do it (realtime). Can someone confirm?

How to change default folder for opening files with SciPad (XP pro)?
Thanks.

How to change the font (family, style etc.) of the command window. In
this group I found a description how to change the size but that
appears not to work for the font style.
