MATLAB: Counter odd numbers in ‘randi’

odd

counter of odd numbers in 'randi'?

this is program:

a=randi([0 27],1,50);
b=zeros(1,numel(a)*3+numel(a));
b(4:4:end)=a(:)

what is need write after that?

Try this:

a=randi([0 27],1,50)
numberOfOddNumbers = sum(rem(a, 2))

MATLAB: How to randomize a sequence of random numbers

repmat just repeats the input matrix. So, for what you want, the repeated matrix must change. I think the easiest way is like:

seqVectorX = [];
for i = 1:13
    a = randi([1 4]);
    b = randi([1 4]);
    c = randi([1 4]);
    d = randi([1 4]);
    
    ASRTT = ([1 (a) 2 (b) 3 (c) 4 (d)]);
    
    seqVectorX = [seqVectorX ASRTT];
end

And the next example makes the random numbers at first, then they are inserted to numbers in order.

v1 = repmat([1 2 3 4], 1, 13);
v2 = randi([1 4], 1,4*13); % random numbers
seqVectorX = reshape(cat(1,v1,v2),1,4*13*2);

Does this meet the objective?
