Details:


address@hidden ~]$ echo "MW,,3.4,5.5" > test.csv


strictly speaking column 1 and 2 are NaN

first let's take a look what matlab did :)
 
 

>> csvread('test.csv')
Error using dlmread (line 139)
Mismatch between file and format string.
Trouble reading number from file (row 1u, field 1u) ==> MW,,3.4,5.5\n
 
Error in csvread (line 48)
    m=dlmread(filename, ',', r, c);
 
>> 


 
 
and what octave did
 

octave:1> csvread('test.csv')
ans =
 
   0.00000   0.00000   3.40000   5.50000
 
octave:2> 



for me, this is fine too and there is no need to copy matlab behavior! but
maybe there should be an option how octave should handle empty values?
parse them as NaN or parse them as 0
