Generate rand of two specific numbers and not a range

I have generated a matrix of an image and im trying to generate the rand function to pick between two specific numbers and not a range of numbers. So lets say I want the third row of the third column to be either 1 or 50, randomly picked. how exactly do i make that pixel be equal to random number equation that i made?

Hi, One way for this is as below

val = [1,50];
r = randi([1, 2], 1); % Get a 1 or 2 randomly.
Value = val(r) ;

Replace with the random value

Img(3,3)= Value; % the example you mentioned

Hope this helps
