Why return function min in matlab return two values?

Hi guys !

Im using min function that's already built in matlab over an integer array like arr1=[1 2 3 4 5 6 7];

my problem is that min() returns two values(it's really weird !), first value if the min value of the array values, the other value I don't know what it's any help?

for instance:

[x y]=min(arr1) %arr1 is integer values
[x z]=min(arr2) %arr2 is integer values
[x m]=min(arr3) %arr3 is integer values

I get:

y= 1 , z=2 , m=1 .

the value x is the minmum value of the array.

so the second value that min return is 1 or 2 ..so what's this value about? could anyone please help me what this second value that min return is?

thanks alot!

The 2nd value is the index number within the array where the min value is. From the help:

[M,I] = min(X) also returns the indices into operating dimension

corresponding to the minimum values. If X contains more than one

element with the minimum value, then the index of the first one

is returned.

Appreciated !

first value if the min value of the array values, the other value I don't know what it's any help?

If so, why haven't you googled the documentation?

Paras, you should post your answer in an Answer field rather than a comment.
