max
returns a vector containing the maximum value of each column.
When given a vector,
max
returns the maximum value:
>> max(m)
ans =
9
To find the index corresponding to the maximum value, supply two out-
put arguments to
max
:
>> [v,ind] = max(m)
v=
9
ind =
2
The first argument is the maximum value and the second is the index of
the maximum value. Another example is
>> x = 0:.01:2;
>> y = humps(x);
>> plot(x,y)
>> [v,ind] = max(y)
v=
96.5000
ind =
31
>> hold on
>> plot(x(ind),y(ind),'ro')
>> x(ind)
ans =
0.3000
>> y(ind)
ans =
96.5000
