hi, whenever I try to use min() on a vector I get the error message: Subscript indices must either be real positive integers or logicals.
Below is an example
>> d
d =
3.4546 1.1588 4.6319 2.5456
>> min(d)
Subscript indices must either be real positive integers or logicals.
Please can sb help? Many thanks,

Don't define a variable named min. If you do, then you get that exact error when you try to use the FUNCTION named min. IF you don't believe me, then try this:
which min -all
What does it tell you?

@Xiaoyan: we know what you want to do. Please run this command and tell us exactly what it prints:
which min -all
