Create array with 7500 1s, 5000 2s, 8003s etc.

I'm new to matlab, and I have to create a histogram based off a picture where the values are 7500 1s, 2500 2s, 800 3s and 100 4s. I think if I can get a row array with all those values (Order doesn't matter) I can make the histogram.

I also need to turn the row vector into a column vector

What have you done so far? What specific problems are you having with your code? Do you know how to construct row or column vectors of constant values? Do you know how to create a histogram?

Hint, to create an N-element row vector with constant value V:

x = V*ones(1,N);

Hint, to turn a row vector into a column vector:

x = your row vector
y = x(:);  % <-- y will be a column vector
y = reshape(x,[],1);  % <-- another way to get a column vector

[Caleb Lindsey]

x=V*ones(1,N) and y=x(:) were exactly what I needed thank you very much!
