min() Subscript indices must either be real positive integers or logicals.

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?

I dont think I have variable called min?... I just want to use min() as a function to search the minimum value in a vector

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

which min -all

Excuse me. And the solution is? Edit: Thank you! I understand! lol.
