Hello beautiful people,

Can anyone tell me that how I get random pair out of the following pairs?

I have these six pairs (1,5) (2,5) (3,3) (2,4) (2,5) (4,2)

these pairs represents x, y values/dimensiuons so I need one random pair like (2,5)....

How are these pairs currently stored?

This seems equivalent to just choosing a random number from 1-6, so you could do

idx = randi(6)

and choose the corresponding pair.

M = [1,5;
     2,5;
     3,3;
     2,4;
     2,5;
     4,2;];
xy_random = M(randi(6),:);
str_input = sprintf("(%d,%d)",xy_random)
str_input = "(2,5)"

a = b(idx(1), idx(2)) + c
