MATLAB: How to remove an element in an array if this element is smaller than 1

relational operationsremove elements

Hi, Everyone,
There are two arrays with the same size. For example: A=[1, 0.5, 2, 0.75, 3, 0.85, 4, 5]; B=[1, 2, 3, 4, 5, 6, 7, 4]. How to remove an element in A if this element is smaller than 1 OR this element is larger than the corresponding element with the same index in B?
I used the following line but it didn't work:
A((A < 1) | | (A > B)) = [];
MATLAB returned the following red lines: "Operands to the and && operators must be convertible to logical scalar values."
The result I want is A=[1, 2, 3, 4].
At the same time I also want to do the same operation to B. If the element in A is smaller than 1, the corresponding element in B will be removed, and if the element in A is larger than the corresponding element in B, that element in B will also be removed. So the resultant B I want is B=[1, 3, 5, 7].
Hope someone can help. Many thanks.

Too many |. Try this:
A((A < 1) | (A > B)) = [];
