Question

A=[ 2 4 8 20 0 0;
    1 3 6 18 22 0;
    0 3 5 8 18 20]

and then from the above matrix, I want to account average of max value of every rows.
so I wish the result :

result=average(20+22+20)=20,67

thankf for your help.

Answer 1

[C,I] = max(…) finds the indices of the maximum values of A, and returns them in output vector I. If there are several identical maximum values, the index of the first one found is returned.

for your problem

maxValues= max(A,[],2)
result=Mean(maxValues)
