I kept getting some crashes, and found it to be caused by a line that
can be stripped down to this:
disp(ascii(13)+"a;")
Is there a logical explanation?

The main problem I ran into with csvRead was reading files with a
variable number of separators in each row. Then my suggested solution
pads with 0. It could be changed to pad with NaN also.
Using strsplit in each row allows for several separators in the same
conversion. It may still be
Hi Daniel

csvRead is quite strict regarding column structure etc, but the
associated error message is typical "can not read..". So when it
reports "does not exist", it looks like the file is missing, or
misplaced. If you still think the file is there, you may try this script

I find it safer to process the data without returning to a disk file. As

binary, as then all byte values are accepted.

To find out how long the file is (although not strictly necessary) I
normally use:

mseek(0,fid,'end');

it up if it is big) : data=mgeti(lef,'c',fid);

Yes, I thought that would be easier. But still not as good as it could
be, as it is difficult to use these function calls directly in
expressions. This is the way I think it should be done in Scilab 6:

As a quick fix, would it work to use a temporary file for the data you

Would this work? Read as much as you need as binary and convert the non
ascii values to an ascii value, for instance 0.
The below is not optimized, and I have no idea why the strsplit is
needed, but I got an "unknown error" without it:

The only added bonus with the uicontrol is that you have access to a

What would a callback bring anyway, that you cannot do with xclick() ?
Well, callbacks are the "official" way of interacting with the user.
It would allow you to create an intereface in a consistant way, using only

Have you tried plot() and replot()? You can do quite a bit with that by
using LineSpec and GlobalProperty. The example below includes plotting
with primary and secondary Y axis:

I tried to run your function in Windows 10. Memory usage climbs
gradually here also, but when it reaches 90% some action is taken, and
it drops to about 85%. This goes on repeatedly, so I have not yet
