Both vi and emacs can handle vary large files. You could use either to
replace all
separatots by commas and then use csvRead.

Hello,
Does an implementation of the Radon transform exist in Scilab, similar
to the Matlab
"radon" function ? Would anybody be willing to share a homemade version ?
Thank you for your input

Hello,
I wish to use orthogonal polynmials within Scilab. Axxording to
"ttps://atoms.scilab.org/toolboxes/Ortpol", I do
atomsInstall('Ortpol')
that it is available for Scilab 6.0
on Windows.
If it is, run atomsSystemUpdate() before trying atomsInstall(..) again.
Where did I go wrong ? Is there a workaround ? Thank you in advance for
your help.

Hi Claus,
I tried to post an example of a stacked 2D plot but my post was held up
due to a too large graphic
file (postscript). I have now converted this plot to png format. Here it
is. Ypu may still be interested
in using the xpoly function, despite seeing Samuel's beautiful examples

Hi Claus, Rafeal and Samuel,
Here is another method for stacked plots, which was suggested to me
years ago by Serge Steer.
I used it succssfully for about 12 individual curves.
Cheers,

Hello,
I would like to know whether and how it is possible to program
individual pixels within a Scilab figure ? I have in mind a simple
application: a disk moves inside a bounded region and changes the colour
of every pixel it sweeps over. Thanks for your hints.

Hello everybody,
Using Scilab (6.02/Win7), I have drawn a picure made up of thick lines
and arcs, within a region with irregular borders. The backround is
white, all lines are black. Now I would like to count the number of
black and white pixels. Any idea on how I could do that ?
Thank you
My thanks to all respondants.
The figure is in internal Scilab firmat made up of polylines., the
border is a polygon.

I am mainly interested in obtaining the ratio (number of white

Hello Philipp,
Thank you for your program, it looks like it would do exactly what I
wanted. However (as I should have stressed before) I work under win7. In
this environment, the only image processing toolbox is IPCV in which
several functions are lacking, namely
scicv_Init();
Hello,
I have stumbled upon the following strange behavior of function "isreal"

--> isreal(z(1))
ans =

What did I miss ? Rhank you for your help.

Dear all,
I am drawing a graph in a gray scale (say from 1 to 32), using lines of

two lines, the shade of gray be the sum of the densities of each line.
How can I manage that ?

Thank you all fior your multifaceted and interesting suggestions. A
special mention to Christophe: the pages on the SVG format are extremely
clear; in my opinion, they deserve a wide audience and should be
translated in English.
