Hello,
With Scilab 6.0.1 under OSX or Linux, and your script
len = 10000 ;
fid = mopen(fullfile(TMPDIR,'Scilab.bin'),'wb+');
mput (int16([1:len]), 's', fid ) ;
mt1 = mtell(fid) ;
mseek(0, fid) ;
rm = mget(len, 's', fid);
mclose(fid);
printf('%i %i', mt1, length(rm))
I got the expected answer:
20000 10000
--> mt1
mt1 =
20000.
However, I confirm that under Scilab 6.0.1 under Windows 7 I got the
same result as yours:
20296 25
--> mt1
mt1 =
20296.
This is somewhat related to
https://antispam.utc.fr/proxy/1/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/bugzilla.scilab.org/show_bug.cgi?id=3684
In order to have the correct behavior change "w+" to "wb+" in the mopen
I will create a bug report on
https://antispam.utc.fr/proxy/1/c3RlcGhhbmUubW90dGVsZXRAdXRjLmZy/bugzilla.scilab.org

Hello,
I try to go from MatLab to SciLab.
I am a little disturbed by my first tests, maybe the change of
context ...
I'm probably using the instructions incorrectly, but my mistake is so
huge
that I can not see it.
Can you help me open my eyes?
The following code:
*
len = 10000 ;
fid = mopen( 'C:\Users\yoon\Documents\MATLAB\Dorian\SciLab.bin' ,
'w+' );
mput ( int16([1:len]), 's', fid ) ; mt1 = mtell(fid) ;
mseek( 0 , fid ) ;
rm = mget(len, 's', fid);
mclose(fid);
printf('%i %i', mt1, length(rm))
*
creates a file of 20296 bytes. I expected exactly 20000...
mt1 == 20296.
Moreover "mget" reads only 25 short words.
If I simply changes "[1:len]" for "zeros(1,len)", every thing becomes
ok,
(file size and rm length).
If I use double words instead short " mput ( [1:len], 'd', fid ) ; "
the file size is 80040 and rm's length 2060 !!!
What's missing me?
Thank's in advance,
Yannick
