How many positive entries in array

I have a 1450x1 array. I want to count how many positive entries in array?

Answer 1

[Wayne King]

x = randn(1450,1);
indices = find(x>0);
length(indices)

or

count = length(nonzeros(x(x>0)));

Answer 2

Or you can use for an array:

x = randn(1450,1);

sum(x>0)
