MATLAB: Two random number columns

random number

I need to genarate a series of random number from 0 to 1 using rand(5,1). against same list I need a random list of 0 and1 in second column Both must be assocated so I can use in program

e.g

0.1058 0

0.1097 0

0.0636 1

0.4046 1

0.4484 0

MATLAB: How to create a symmetric random matrix

Let the random matrix to be generated be called M and its size be NxN.

   d = 1000000*rand(N,1); % The diagonal values
   t = triu(bsxfun(@min,d,d.').*rand(N),1); % The upper trianglar random values
   M = diag(d)+t+t.'; % Put them together in a symmetric matrix

If you want whole numbers, apply the 'floor' function to 'd' and then after computing 't', apply it to 't'.

 mean2 = mean(D(:,4:5),2),
 mean3 = mean(D(:,6:7),2),

 D1 = [37.8518   22.2652   45.1886   38.1301   50.4733   15.3074    4.4514;

 meanData =
