[Scilab-users] read format

[grivet]

Your suggestion does not work for me. Here is what I get:
-->M = csvRead('dataN.txt', ';', "double");
  -->M(1:10,:)
  ans  =
      Nan    5.49    1.
     Nan    5.49    1.
     Nan    5.48    1.
     Nan    5.48    1.
     Nan    5.48    1.
which seems to check with the help for csvRead:

When the input argument "conversion" is equal to "double", the 
non-numeric fields within the .csv (e.g. strings) are converted into NaN.

Thank you for your time and help.
