Hello everyone.
I am new to Matlab and therefore have a few questions regarding generation of random numbers.
My task is to randomly generate numbers for age between 18 and 121 - we need 11000 numbers. Afterwards we need to figure out male and female (0 is females) which I'm having difficulties with.
I know I have to use rand function but I cant figure out how to complete these tasks.
Can someone please help me with some guidance for this? Thank you in advance.
Kind regards, Emil

Read the help for rand. Do so CAREFULLY. If necessary, do so twice. Look at the examples given in
doc rand
Your vague question about males and females is impossible to even try to answer, because there is no real question there.
So spend some time actually learning MATLAB. Read the help. My guess is, you need to read the getting started tutorials first.

Emil, try this:
rInteger = randi([18,121], 1, 11000) % Whole numbers.
rFloating = 18 + (121-18) * rand(1, 11000) % Includes fractional parts
