how to use fscanf in matrix

I have the coding like this:

file2='PDF_Repi_Mw_PGA_Amax.txt';
fid=fopen(file2, 'r');
PMP=fscanf(fid,'%g %g %g %g', [4,Inf])';

Repi=PMP(:,1);            % Distance 
Mw  =PMP(:,2);            % moment magnitude
PGA =PMP(:,3);            % PGA at ground surface
amax=PMP(:,4);            % peak ground surface acceleration

tha data contain every element has 178 row but I don't know the coding read the data only 112 row.

I don't know why? Any one can help. I would appreciate. Thx

try the import tool and see how it deals with the data. This should give you a hint to what's going wrong
