I'm trying to loop through all rows and columns of a random matrix to test whether each element is greater than 0.5
I have this (which, clearly is not working):
for random_number_matrix = rand(4,8)
if random_number_matrix>0.5
display ('greater than')
end
end

random_number_matrix = rand(4,8);
isGt=(random_number_matrix>0.5);
display(random_number_matrix(isGt))
