It is OK if you want to stick to C-style IO but to do it correctly you have to use %g instead of %d.
the results you get are wrong because you input your data incorrectly.
c.
But when I am checked, I cant figure out those. Can you please check this..
My input is a file 'buffer' with 1024 number of samples. My octave program is.
load 'buffer'
setenv ("GNUTERM", "x11")
l=1024;
v=fft(buffer,l);
V = abs(v);
save output V;
and my c++ interpreter program is
fp = fopen("buffer","r");
if (fp == NULL)
return 0;
for (ucI=0; ucI< 1024; ucI++)
fscanf(fp, "%d\n", input_vector.fortran_vec () + ucI);
fclose(fp);
octave_value_list input;
input(0) = input_vector;
octave_value_list output = feval ("fft", input, 1);
octave_value_list final_output = feval ("abs", output, 1);
ColumnVector output_vector = final_output(0).column_vector_value ();
Whats wrong here? Can you please help me.
