How to use the min() and max() functions?

I am trying to use min() and max() to find the minimum and maximum values of a vector (attached to this post if you would like to try)

According to the Mathworks website, using minVal = min(FHNout); and maxVal = max(FHNout); should work.

However, when trying these commands, I get the following error:

??? Subscript indices must either be real positive integers or logicals.

Why am I getting this error and how do I fix it?

Thanks for your help

If you want to use min or max, then don't name a variable with the name min, or max.

which min -all
which max -all

What does that tell you?

Never use variable names that conflict with a function name.

Thanks so much. That fixed the issue. There was another variable in my work space called min and max
