How to read .csv file in Scilab.

[qingx...@gmail.com]

Hi,
I'm learning Scilab now, I wonder how to read .csv data to variables.
For example I got the following error:

-->[fid,err] = mopen('test1.csv','rb')
err =

0.
fid =

1.

-->xxx = read(1,11,8)
!--error 243
C file logical unit not allowed here

!--error 49
incorrect file or format

The data in the file basically look like

ABS
-30
30
10
5
0.35 0.346 -1.142859
0.177 0.205 0.238 0.279 0.314 0.371 0.409 0.444
0.169 0.206 0.243 0.29 0.323 0.374 0.411 0.435
0.161 0.203 0.231 0.272 0.321 0.364 0.399 0.428
0.162 0.197 0.221 0.269 0.312 0.368 0.399 0.42
0.153 0.185 0.22 0.274 0.313 0.356 0.382 0.42

etc.

Thanks a lot for your help!

I would use something like:

fd=mopen("myfile.csv");
// read header
he=mgetl(fd,6);
// process header
// ... use msscanf on he elements ...
// read data
da=mgetl(fd,-1);
mclose(fd);
//process data
//...
