MATLAB: Repeating numbers in matrix

repeat columns

I need to generate a input variation in the form

   % For wxample
col1 :2 4 6 2 4 6 2 4 6 2 4 6
col2 :1 1 1 1 1 1 2 2 2 2 2 2
col2 :5 5 5 5 5 5 5 5 5 5 5 5

is there any shorter way to do it without looping.

Best Answer

col1=repmat(2:2:6,1,3)
col2=reshape(repmat(1:2,6,1),1,[])
col3=5*ones(1,12)

Read the documentation

doc repmat
doc reshape

Given c is a cell array of your initial data, then

t=cell2table(c,'VariableNames',{'Line1','Line2'},'RowNames',cellstr(num2str([1:size(c,1)].','Col%d')))
t =
  8×2 table
            Line1    Line2
            _____    _____
    Col1    'L1'     'B'  
    Col2    'L2'     'B'  
    Col3    'L3'     'A'  
    Col4    'L4'     'C'  
    Col5    'L5'     'B'  
    Col6    'L6'     'C'  
    Col7    'L7'     'C'  
    Col8    'L8'     'A'

For such data, however, I'd strong recommend using categorical

>> t=table(categorical(c(:,1)),categorical(c(:,2)),'VariableNames',{'Line1','Line2'},'RowNames',cellstr(num2str([1:size(c,1)].','Col%d')))
t =
  8×2 table
            Line1    Line2
            _____    _____
    Col1    L1       B    
    Col2    L2       B    
    Col3    L3       A    
    Col4    L4       C    
    Col5    L5       B    
    Col6    L6       C    
    Col7    L7       C    
    Col8    L8       A
