how to find out how many columns have more than 50 elements which are greater than 1?

2 views (last 30 days)
I currently have a matrix that's 100*100 size, and I wish to work out how many columns have more than 50 elements which are greater than 1. Is it possible to do it using only rudimentary functions like find(), mod(), length(), numel(), etc?

Lets say matrix 100*100 named as data
idx=data>1;
result=sum(idx);
data2=result>50;
fprintf('The column number is: %d',sum(data2(:)));

x = rand(100) * 2;
atLeast50 = sum(x > 1, 1) > 50;
