Index exceeds matrix dimensions when finding max value

Question

I have been trying to find the max value from an array. But I keep getting the following error. Please advise.

scores = [19212       56722       73336                


        

Answer 1

you probably have a variable called max. Try

clear max
max(scores)

Answer 2

Have you defined an array called max ?

scores = [19212       56722       73336       44805       47268 ]

max(scores)

ans = 73336

If I define an array called max

max=[1:10]

max(scores)

??? Index exceeds matrix dimensions.

Check by using the which function

which max

max is a variable.

It should be

which max

built-in (C:\Program Files\MATLAB\R2009a\toolbox\matlab\datafun\@logical\max)  % logical method

Answer 3

To get the indices of the maximal value: scores=1:10; find(scores == max(scores))

If you have two maximum values:

clear max
scores=10:-1:1;
scores=[scores 10];
find(scores == max(scores))

ans =

     1    11

As you might guess max return the max of an array:

>> max(scores)

ans =

    10
