I have a problem with dlmwrite.
The code attached in bam.m works fine on matlab producing a normal
matrix
file. In octave, however, it produced the file qjbx0203 that I also
attached
with a "g" following every number. Octave itself is not able to read
this
crazy file. This is a real problem for me because I need such files and
have
only limited possibilities to make them on matlab. Could you please
help
me?
I believe you forgot to attach the file. Try using pastebin.com
instead of attaching files.
Sorry. Here it is:
bam.m:
a=load('qjbx1203');
a=spconvert(a);
b=load('qjbx013');
b=spconvert(b);
c=a*b;
[q1,q2,q3]=find(c);
q=[q1 q2 q3];
dlmwrite('qjbx0203',q,'delimiter',' ','precision',20);
clear;
qjbx0203:
1g 1g 6g
2g 2g 2g
3g 2g 2g
4g 3g 2g
You forgot to also reply to the mailing-list. It's better to keep
conversations there so that everyone can help. Also, you didn't attach
the files with the original matrix (qjbx1203 and qjbx013).
Anyway, I can read the file generated with dlmwrite, no problem, with
dlmread. Try:
dlmread('qjbx0203')
You could use the command 'save' to save the matrix into a file as well.
Thank you for your advice. Now I have an even simpler example:
bam.m:
q=[1 2 3; 4 5 6];
dlmwrite('testcsv',q,'delimiter',' ','precision',20);
clear;
testcsv:
1g 2g 3g
4g 5g 6g
If I use the command "save" this changes the format, I want it as a csv to
leave it compatible with something else. Up to now, I tried to read files
with "load". Even if I can read those files with dlmread, the additional "g"
after each number will cost a lot of disk space so the best thing would
still be to eliminate it. There was something about this on the bug tracker
under bug #29870 but I could not use the solution because the mentioned file
does not exist on my system. Can you help my?
I don't know what that g stands for. But it disappears if you drop the
precision=20 option
dlmwrite('testcsv',q,'delimiter',' ')
Also, there's others formats that you can use with save. See 'help save'
