What are you trying to achieve, extract the numbers? The space in the pattern ' +' won't match tabs actually, but '\s+' would (match spaces, tabs, any "white space"). If your goal were to extract numbers, you could go for
>> match = regexp(LineText,'\d+','match') ;
>> num = str2double(match)
num =
0 43 0 0 0
If you had a whole file with this structure, you could process it in one shot instead of line by line (for the example, I repeated several times this LineText that you provided and just incremented the AD value)..
>> buffer = fileread('brad.txt') ;
>> num = str2double(regexp(buffer,'\d+','match')) ;
>> num = reshape(num, 5, []).'
num =
0 43 0 0 0
0 44 0 0 0
0 45 0 0 0
0 46 0 0 0
and you could use more elaborate patterns if numbers were not integers, e.g. '[\d\.-]+' for matching positive and negative floating points as well.
