Re: NaN

[Matt Funk]

I am probably too much of a retard, but it gives me:

terminal:
syntax error
>>>     str = fgets(program_input_handle);  # read one line from the opened 
file

for the code snippet:
program_inputfile = sprintf('octave_output/simple_MaxError.dat');       
program_input_handle = fopen(program_inputfile,'r');  
for j=1:5
        junk = fgets(program_input_handle) %grab junk at beginning of file
end
str = fgets(program_input_handle);  # read one line from the opened file
row_vector_of_data = str2num(str)
fclose(program_input_handle);

Anyway, but did it a little different way than you with fscanf and filepoiner 
manipulation. 

thanks anyway
mat
