How to get index number of an element in an array

[bjbdts]

Hi,
I'm calculating a frequency response of a variable. So basicly I have an array of frequency, and I have a corresponding array of the variable. My question is how can I get the index number of the maximum value of the variable?
Is there a simple command?
Thanks for your help.

Type "help max" on the command line (without the quotes, of course).

Hi, I have the same problem but with median function.
So my question is how to get index number of median element (if it exists) in vector/array. (without using for loop)

[val,index]=median(x)
displays error: to many output arguments
It seems that this works only with max/min

Hi, ushy:
I guess the median(x) funcion calculates the median value of your array. For example, if x=0 1 2 3 4 5,
then median(x)=2.5, and 2.5 is not an element in the array.
