MATLAB: How to read the tab delimited with skipping the first row

tab delimited ampl file

I want to skip the first row because the function 'tdfread' cannot read the file with first row "ampl.tab 3 1" File Structure:

ampl.tab 3 1      
r  p  t  Ox
1  1  0  0
1  1  1  0
1  1  2  0
1  1  3  0

I would use the textscan function instead. Something like this would work:

fidi = fopen(filename,'rt');
D = textscan(fidi, '%f%f%f%f', 'Delimiter','\t', 'HeaderLines',2, 'CollectOutput',1);

Experiment with it to get the result you want.

A = reshape(1:24,2,3,4);        % input: [n x m x k] array
val = squeeze(sum(A,2)).';      % output: [k x n] matrix

use

A =[1     2
     1     2
     1     2]
 A(:,1)=0;
 B=A
