To get the column number of max and min number

I have an array,

a=[ 1 5 3 7 4]

How can I get the position of max and min numbere?

The answer should be

max = 4 %(number 7 which is at column 4 )
min = 1 %(number 1 which is at column 1 )

>> a = [1,5,3,7,4]
a =
   1   5   3   7   4
>> [~,mxi] = max(a)
mxi =  4
>> [~,mni] = min(a)
mni =  1

You can use the min() and max() functions but they have a serious limitation with integer numbers - they only return the FIRST occurrence of the max or min. If it occurs more than once you will not get all the indexes. Try this demo code and understand the results:

a=[ 1 5 3 7 4, 7, 1]
[maxValue, indexOfMax] = max(a)
[minValue, indexOfMin] = min(a)
indexesOfMaxs = find(a == maxValue)
indexesOfMins = find(a == minValue)

The results in the command window:

a =

1 5 3 7 4 7 1

maxValue =

7

indexOfMax =

4

minValue =

1

indexOfMin =

1

indexesOfMaxs =

4 6

indexesOfMins =

1 7

Note how using find() gives you both indexes rather than just the first one.
