how to set value for each column?

Hi,

I have an array of 15x10. The first half is pData and the second half is nData. How to set the data in order to get this condition;

1. Each column in 'nData' should have k = '01'

2. Each column in 'pData' should have k = '10'

Here are the data.

26  30  33  36  30  29  28  26  26  27
26  28  30  39  31  28  29  25  29  26
29  32  30  42  32  32  32  26  33  24
30  33  31  43  32  33  33  26  34  24
27  33  37  41  35  31  31  29  30  30
26  35  37  43  33  30  30  29  30  32
23  37  33  40  32  27  32  29  31  34
21  38  32  39  32  27  33  29  32  35
32  28  26  27  26  27  26  27  29  27
36  31  27  29  30  30  30  31  31  30
34  30  28  28  28  30  30  35  30  31
33  29  29  28  27  29  30  36  30  32
30  27  27  26  26  26  25  28  31  27
34  30  30  26  27  30  27  32  34  31
34  27  30  25  28  32  28  36  32  29

This is how I write to divide the array and to treat each column as above condition.

 for i = 1:length(data)
    for n_data = data(:,6:10,1)
        k(i) = 01;
    end
    for  p_data = data(:,1:5,1)
        k(i) = 10;
    end
end

This code doesn't give the expected results as below,

   k 
      10 10 10 10 10 01 01 01 01 01

Please help me to solve this problem. Thank you

Answer 1

[Andrei Bobrov]

A = randi([25 50],15,10);

k = {'10','01'};
n = size(A,2);
k = k(ceil(2*(1:n)/n));

It works!! Thank you very much

Let A be your 15x10 matrix.

B = ones(size(A)) ;
B(:,1:5) = 10 ;

Thanks for your quick reply.

I've checked using your given code.It turns out to be 10(15x5) and 1(15x5).

I don't want to change each element of array A.

I need to appoint for each column from 1 to 5 to have the value of k = '10' and

each column from 6 to 10, to have the value of k = '01'.

In another way, I want it to be like this;

(:,1) -> k = 10
(:,2) -> k = 10
.
.
.
(:,5) -> k = 10
(:,6) -> k = 01
(:,7) -> k = 01
.
.
.
(:,10) -> k = 01

Do you have any idea to do it?

Thank you
