Create a random vector only with positive numbers

Hello, I'm new in matlab and I want to create a vector only with positive numbers.

I usually use the function "randn()" but i can't control the sign of the element.

Thank you! :)

If you don't care what the distribution is, infinite possible recommendations can be made. You can use a classically non-negative distribution, e.g., rand, poissrnd, randi,...

Or, you can improvise and do things like,

x=randn(1,5).^2

x = 1×5

1.2926 0.2196 0.1405 2.3377 0.0006

or

x=abs(randn(1,5))

x = 1×5

0.7789 1.6381 0.6319 0.5479 1.2840

I didn't know these functions!

Really helpful, thank you so much!
