Hello,
I need to read in a csv of about 360.000 lines with date and numerical
values. Attached is a sample excerpt of that file.
So far I did:
CODE
// read in
tic
mydat = csvRead('dat04-2011.csv', ';', ',', 'double', [], [], [], 6);
toc (= 5,213 secs)
mydat = mydat(:,2:6);
tic

But except the empty clf() there are none of my figures at this point. All
my plot functions are following after this...
However putting the clf() below
Under Linux I have the problem that all Scilab application (console,
scinotes, help, figures) have the same icon in the taskmanager, which makes
it very cumbersome to navigate between them.
Is this just me?
Any way to change this?
Note that the windows them self (in the upper left corner) do

Both of these involve the GUI and user interaction, which I BOTH want to
avoid...
Furthermore printsetupbox() doesn't seem to have an effect on the saved pdf

Yes, this is what I'm doing already.
But ofc a link to click on is way more
Hi Samuel,
thanks for the hint, that works nicely.
Regarding xstring is there a way to place it relative in the graph?
I.e. not at a fixed axis position, but at e.g. lower and left 10% of the
graph?

thanks I already figured it out with demo_gui and by searching the archive.
So for the record:
For my case I needed to create 3-axes:
1 for each extra y-axe and one "virtual" to get the x-axe in its own color
scheme.
This is the code I ended up with:

Hello,
I have this problem that when I start scilab from my startmenu, the console
doesn't accept any input and when I execute a script (from scinotes) scilab
crashes.
However when I start scilab from the terminal "scilab &" everything is fine.
Any clues, is this a known issue?
Scilab 6.0.0.
Thanks Jasper & Rafael, these solutions work great!

Hello All,
I have this for loop:
for i=1:size(log_data,'r')-1
energy(i)=(log_data(i+1,1)-log_data(i,1))*log_data(i,2)*log_data(i,3);
end
The rows / loopsize are only a couple of thousands, so it is not that big of
deal, still I was wondering: It is possible to do this w/o a loop?
cheers
Hello Nikolay,
thanks for the prompt reply!
Under Plasma5 I can just check the "Run in terminal" option which also works
then.
However I also replied on the bug, hopefully it will be fixed soon...

Before my printing commands I'm setting up some defaults like this:

defaxh.title.font_style = 9;
defaxh.x_label.font_size = 4;
defaxh.y_label.font_size = 4;
I find it confusing that only "DD/MM/" doesn't require a leading zero,
while all others do...
Also there is no support at all for the us date format (MM/DD/). Not a
fan of it, but users from the USA might appreciate it.

Scinotes has its proper icon in the window, but not in the taskmanager.

Ok, I corrected the syntax and it works now with regard to the nans:

asc_data([a;b]) = %nan;
The black color btw, seems to be from the edge color, if I do
surf(asc_data,'edgecol','white');
it is all white.
How can I turn the egdecolor completely off? preferably via

Ah, thank you, this looks good!
With my syntax:

weren't in asc_data), I suspect some memory issues maybe...

Still, kind of 'meh'. Because this way I cannot access the z-value...
Is there a way to align the text in the box (instead of centered)?

Hi Samuel,
I need the number in "kWh", but no digits after the comma.
Postprocessing with strcat(s," ") is a nice idea.
Is there a function to split the number to the power of 10 factors?
Eg. 2725977 becomes
[2 , 725 , 977]
Then it would be really easy. :-)

Hi all,
thanks for the replies, fscanfMat() does work fine.
I suspected something like this with the changing spaces between the values,

in an csv with several ',' one would indeed expect it to treat these as
