you can try this:

M = dlmread('yorFileName.dat')

[r,c] = size(M);  %get row and column values of data matrix

for i = 1 : c    
    vector = M(:, i);       
end

this result the last column only in matrix ... i need all columns in one vector

You can try and test this:

M = dlmread('yorFileName.dat')

[r,c] = size(M);  %get row and column values of data matrix

C=[]

for i = 1 : c    
    vector = M(:, i);  
    C = horzcat(C,vector);

end
