if you meant to fetch values from a random index using above mentioned linear indices:
a = magic(5);
a = a(1:3,:);
validIndices = [1,3,4,5,8,9,10,11,13,15];
i = validIndices(randperm(numel(validIndices),1));
x = a(i)
but if you meant to use them as subsets (i.e a(i,j)), you have a problem, because these subsets are larger than your specified matrix, and will almost always result in an error
