Histogram in Matlab for data bigger than a threshold

Question

如何为大于数字（例如N）的向量元素绘制向量的直方图（例如B）？

Answer 1

If you generated a column vector of 30 random numbers from a uniform distribution:

x = rand(30,1);

And wanted to use a cutoff of N = 0.3 (from your notation above), instead of using all the values:

hist(x(x>0.3));
