Pls help in solving the below question

Generate 10,000 discrete random variables uniformly distributed in the set {1,2,3,4}. Assign each outcome in this set to one of the signals {(1,1),(1,-1),(-1,1),(-1,-1)}. the sequence of discrete random variables then produce sequence of 10,0000 signal points X.

Answer 1

[Walter Roberson]

See randi() and cell arrays.

Answer 2

[G Newton]

mygeneration=randi(4,1000);
thissig=your signal;
make another cell by reshaping(thissin,size(mygernation))
for i=1=size(mygeneration,2)
%%here try to assing by using for loop
end

[Walter Roberson]

The size will not be right for that randi()
