Generate 2 random numbers x and y for 10 times in a loop. x can take any value in the range of (0,1) but y is conditioned on x such that y assumes any number between (0,1-x)

for i=1:10

random_x=rand

random_y=

You can use the following to generate random numbers between 0 and 1-x

y=rand()*(1-x)
%To generate random no.s between a and b : y = a + rand()*(b-a)

Hi @Payel. Here is the solution and code for your question.

Question: How to use the rand() function when the range parameters are conditioned on any other variable?

Solution:

You can simply define the independent variable first and then use it in defining the dependent variable.

To be more specific, once you define the x, you can use y = rand()*(1 - x).

Code:

x = zeros(1,10);
y = zeros(1,10);

for i=1:10
    temp = rand(1);
    x(1,i) = temp;
    y(1,i) = rand(1)*(1-temp);
end

x

x = 1×10

0.6590 0.7347 0.9144 0.6091 0.3819 0.4112 0.1823 0.8654 0.5492 0.6796

y

y = 1×10

0.3405 0.1315 0.0718 0.1244 0.3935 0.3454 0.7109 0.1107 0.1352 0.1733

You can use this:

for i = 1:10

x = rand();

y = rand()*(1-x);

end
