I am trying to vary a random number generator between a range of vectors, this is my code
ub =[1;1;2;2;2;2;2;2;2;2];
lb =[0.95;0.96;1.88;1.88;1.85;1.85;1.75;1.75;1.65;1.58]
Y = lb + (ub-lb).*rand(10,1)
The result I am getting is a 10x4 double matrix, I want a 10x1 vector.
What changes I should make?

lb = [750,150,8,8];
ub = [850,250,15,15];
id1 = randperm(length(lb),1) ; % select 1 lb randomly
id2 = randperm(length(ub),1) ; % select 1 ub randomly
Y = lb(id1) + (ub(id2)-lb(id1))*rand(10,1)

Great so now what is the size of Y?
You just answer your own question I think.
