Command fscanf does not read zero

Hello,

I am using a command "fscanf", but it doesn't read zero at the end of the line.

A file which I am reading contains this formatting:

1 552.45 1 1 1 0

2 870.38 1 2 2 0

name='test.txt';
fid1=fopen(name,'rt');  
ab=fscanf(fid1,'%4f  %5f  %4f  %4f  %4f %4f',[1,6])

Can you help me to correct it?

I have attached the text file. With your command I am getting this result below.

It ignores zero and reads number "2" from the second line.

1.0000 552.4500 1.0000 1.0000 1.0000 2.0000

870.3800 1.0000 2.0000 2.0000 0 0

This looks correct to me:

fid = fopen('test.txt','rt');
mat = fscanf(fid,'%f',[6,Inf]).'

mat = 2×6

1.0000 552.4500 1.0000 1.0000 1.0000 0 2.0000 870.3800 1.0000 2.0000 2.0000 0

fclose(fid);

For comprison:

type test.txt

     1  552.45             1         1         1         0
     2  870.38             1         2         2         0

Your width field is not wide enough for the second field, so the trailing '5' is read as being the next field.

name = 'test.txt';
fid1 = fopen(name,'rt');  
ab = fscanf(fid1,'%4f  %5f  %4f  %4f  %4f %4f',[1,6])

ab = 1×6

1.0000 552.4000 5.0000 1.0000 1.0000 1.0000

frewind(fid1)
ab = fscanf(fid1,'%4f  %6f  %4f  %4f  %4f %4f',[1,6])

ab = 1×6

1.0000 552.4500 1.0000 1.0000 1.0000 0
