how I can remove head of file

I have the following code:

fid = fopen('h.csv', 'rt');

for i = 1 : 4 : size( h,1 )

disp( h( i : i + 3,: ) )

disp(['[*,*,' num2str((i + 3)/4) ']: 1 2 3 4 5 6 7 8 9 10:='])

end

The out put is :

VarName1 VarName2 VarName3 VarName4 VarName5 VarName6 VarName7 VarName8 VarName9 VarName10 VarName11

Hey Sherek,

I believe that you have not provided the complete code snippet as the variable 'h' is not defined. Since your dataset appears to be having only numerical values, I recommend you to use the readmatrix function:

fid = fopen('h.csv', 'rt');
h = readmatrix('h.csv'); 
disp( h( 1 : 4,: ) );

   51.6000 -150.7200   -2.0019  103.6500  -70.6260  -22.0920   66.0560  -40.3930    0.1683   10.8980       NaN
  106.4000 -295.1700  -64.9310  324.5700 -238.1900  -82.3530  345.9600 -384.9300  255.5400 -100.1400       NaN
  107.6000 -289.4400  -88.5180  357.1400 -262.2900  -72.9360  341.1000 -378.4800  244.7900  -93.1390       NaN
  112.5000 -294.1200 -115.5900  405.7700 -297.5000  -71.4680  371.7700 -416.4400  271.8300 -104.0000       NaN

On the contrary, if you need to display the headers, I would suggest you to use the readtable function:

T = readtable("h.csv");
disp(T(1:2,:));

    VarName1    VarName2    VarName3    VarName4    VarName5    VarName6    VarName7    VarName8    VarName9    VarName10    VarName11
    ________    ________    ________    ________    ________    ________    ________    ________    ________    _________    _________

      51.6      -150.72     -2.0019      103.65     -70.626     -22.092      66.056     -40.393     0.16829       10.898        NaN   
     106.4      -295.17     -64.931      324.57     -238.19     -82.353      345.96     -384.93      255.54      -100.14        NaN   

fclose(fid);

I hope this helps!
