For example, if there is the variable x;
x = [1 1 1 1 1 1 1 1 0 0 0];

Ran in:
x = [1 1 1 1 1 1 1 1 0 0 0]
x = 1×11
1 1 1 1 1 1 1 1 0 0 0
has_more_ones = mean(x) > 0.5 %note that exactly equal does not qualify as "more"
has_more_ones = logical
1

Another way (assuming only 1s and 0s in the array):
moreOnes = nnz(x) > numel(x)/2
