Problem with Matlab script

[Riedel Thomas]

Hi guys,

i have a problem with a matlab script i like to run in Octave.
The commands below do not result in an output of a text file 
(Results_formulas.txt).
I suspect that the matlab syntax for "fprintf" does not work here, but 
i cannot figure out the error.
Many thanks for your help,

Thomas!


output_file = ['Results_formulas.txt'];
data = [a;b;c;d;e;f;g;h;i;j;k;l;m;o;p;q;r;s;t;u];
fid = fopen(output_file,'wt');
fprintf(fid,'%4.5f %4.6f %2.0f %2.0f %2.0f %2.0f %2.0f %1.0f %8.0f 
%5.0f %3.0f %4.2f %1.5f %2.0f %2.0f %7.0f %1.0f %1.0f %1.0f %1.0f\n', 
data);
