[scilab-Users] reading file in hexadecimal

[Mike Page]

Hi Loic,

Not sure what you want exactly, but the file looks like a set of floats
(4-byte IEEE 754 floating point values).  You can read these using:

a = mget (n, 'f', fd)

where n is the number you want to read and fd is the file descriptor (you
get that using fd=mopen("F1_31.dat",'rb').

If you really want the values in hex, then it depends on how many bytes per
hex value.  If there are 4 bytes each, then you can use something like:

a = dec2hex (mget (n, 'l', fd))

Hope that helps.

Mike.

  Hello,



  Beginner under scilab, I’m trying to make a script to read a file and make
some calculations on the data.

  I would like to read the file attached (F1_31) as an hexa format.

  For the moment, I use notepad++ to convert the file in hexadecimal and I
can read it in scilab using mopen/mfscanf.



  I would like to be able to read the file directly under scilab, without
using another software.



  Is it possible ?



  If yes, could you please explain me the procedure ?



  Best regards





  Loïc
