Cannot get simple matlab programs to run in octave 3.0.0

[Praedor Atrebates]

I have a set of simple matlab programs that I have been trying to get running 
in octave 3.0.0 without success.  

I have a bunch of datafiles containing two columns of data, thus (partial):

-4.220000E-2    4.274234E-1
-4.219600E-2    4.270094E-1
-4.219200E-2    4.272766E-1
-4.218800E-2    4.273062E-1
-4.218400E-2    4.275531E-1
-4.218000E-2    4.272766E-1
-4.217600E-2    4.274953E-1
-4.217200E-2    4.275594E-1
-4.216800E-2    4.275188E-1
-4.216400E-2    4.270891E-1
-4.216000E-2    4.271687E-1
-4.215600E-2    4.270141E-1
-4.215200E-2    4.271734E-1
-4.214800E-2    4.273188E-1
-4.214400E-2    4.275016E-1
-4.214000E-2    4.275141E-1
-4.213600E-2    4.271406E-1
-4.213200E-2    4.274656E-1
-4.212800E-2    4.273219E-1
-4.212400E-2    4.269547E-1

I have a set of matlab programs and functions that takes thousands of files 
containing data like that above and combines it into one single big file.

The initial processing program contains (for the moment) just:

# Rawdata read-in program.
# The parameter 1: the pitch length;
# The parameter 2: start position;
# The parameter 3: number of tracks; 
# The parameter 4: The forth is pixel number for one period of scan; 
# The parameter 5: The path to the folder keeping rawdata

# ILscan1 = 
Getting_RawData_single_channel(0.015,-42,2400,12500,'C\Data\praedor\custom1038-2155\scan1\');
 ILscan2 = 
Getting_RawData_single_channel(0.015,5,2620,12500,'/home/praedor/smb4k/bind222-ml/Data/praedor/custom1038-2172/scan2/');
# ILscan3 = 
Getting_RawData_single_channel(0.015,0,2700,12500,'c\Data\praedor\custom1038-2155\scan3\');

I simply uncomment the appropriate line and edit the path to the rawdata.  In 
the above example my ILscan2 line is uncommented and points to rawdata for 
processing in the samba directory listed.  That location contains 2620 files, 
each containing data like that listed above.

The Getting_RawData_single_channel function is:

    # SurAnal.m
# 2D Analysis program for PC disks and chips
# Creates surface topology, then demodulates the carrier frequency


# User Input            # User modified parameters
function IL = 
Getting_RawData_single_channel(itrack,startrackpos,endtrack,endtime,folderpath)
startrack = 1;          # Starting track number
wspin = 1200;           # Spin frequency
startime = 1;           # Starting time
dt = 1e-6;              # time increment


fname = [folderpath,'rawdata'];

periodic = 0.9042*1024; # adjustable carrier frequency
df = 20e3;              # demodulation bandwidth (30e3)
dny = 0.2;              # demoduulation radius width (0.80)

#S = pwd;
#[s1,s2] = size(S);
#dat = S(s2-4:s2);

dtrack = endtrack-startrack+1;      # Size of matrix in radius dimension
dtime = endtime-startime+1;         # Size of matrix in time dimension

# Loop through tracks
tracknum = startrack - 1;
for trackloop = 1:dtrack
    tracknum = tracknum +1;
    
    x = 1:dtime;
    t = dt*x;
    
    trackname = startrackpos + (tracknum-1)*itrack;

    filnam = [fname, num2str(trackname,'#5.4f')];
    fid=fopen(filnam);
    [a,b]=fscanf(fid,'#f    #f\n',[2 inf]); 
    status = fclose(fid);
    
#    temp = a(2,startime:endtime);           # amp data values
    #avg2 = mean(temp2);

#    temp2 = a(3,startime:endtime);           # phase data values
    #avg = mean(temp);
    #yphase = (temp - avg)/avg2;
    
    
# Subtract linear drift in data
   
IL(trackloop,1:dtime) = a(2,startime:endtime); #temp(1:dtime);        # 
Amplitude topology
endfor     # trackloop

return;

As far as I can tell there is nothing in either program/script/function that 
isn't compatible with octave, but I am a newbie to octave.  

When I try to run the Image_prep program in qtoctave I get:

>> Image_preparation_withoutlandremove
error: fscanf: invalid stream number = -1

If I try to run the program from the octave CLI I get nothing.  No output, no 
error messages, nothing.

What is wrong?
