Re: how to use textscan with gnu octave 3.6.2

hi philip 

Thank you very much for your reply it has helped me a lot. i use fgetl
because there are too many header lines (more than 50) and as you said  the
number of header lines vary between files. 
You can fine an example of the attached -file.
test.txt <http://octave.1599824.n4.nabble.com/file/n4648825/test.txt>  
I wrote the code as you said 
"B = textscan(fid2, '%f = %s%f%f%f%f%f%s', 'delimiter', ';', 'headerlines',
1);"
and i got the results i was expecting.

Know i need this result to do a bilinear interpolation. The code i wrote is
the following

result =  -ones(num_pos, 1);
 if strcmp(property(row_id), 'Aktiv') == 1
             result(row_id, 1) = (1 - r) * (1 - s) * kf_mat(x0, y0) + ...
                                 (1 - r) *      s  * kf_mat(x0, y01) + ...
                                      r  * (1 - s) * kf_mat(x01, y0) + ...
                                      r  *      s  * kf_mat(x01, y01);
           else
                    result(row_id) = -2;
           endif
result

Octave should do a bilinear interpolation just when the canal is 'Aktiv' .
but i think the command strcmp doesn't function this way. on the
command-window i get just  "-2 " everywhere.  When i write the code this
way,

result(row_id, 1) = (1 - r) * (1 - s) * kf_mat(x0, y0) + ...
                                 (1 - r) *      s  * kf_mat(x0, y01) + ...
                                      r  * (1 - s) * kf_mat(x01, y0) + ...
                                      r  *      s  * kf_mat(x01, y01);
the command -window gives me the right results.

Please do you have an idea how i can use strcmp in this case? 
This is the complete code if you need it

Thank you  for your help.
