I could do that but it's messy and it should not be difficult to do in Matlab - I have screwed up though....
fi(fft_out0,0,36,0) is not a fractional number at all - Matlab puts it in exponential form which is described at the top of the list about 100 page-scrolls back...... This might make the rest of what I'm doing make more sense.. Matlab always put's me in a good mood.....
