extracting a particular element from a matrix

Hi all,

I have a column matrix A (with some common elements in it) and another column matrix B, I have added both the matrices (let the final matrix formed is C). Now I want to extract that element from C, which is formed by the max. value among common elements in A and its corresponding element in B

Suppose

A=[1

2

5

5

10

10

10]

B=[1

3

4

5

7

1

6]

Please help to have my answer as 17 from (5th element of A + 5th element of B

Here both A & B are user defined thus the size and index values may differ

[madhan ravi]

why not just:

[Value,Index]=max(A+B)

I Didn't Understand Exactly What you want.

Are You Trying To Find The Maximal Value Of C, I.E 17, Or The Maximal Value For Each Group Of Numbers In A, I.E [2; 5; 10; 17] Corresponding To The Number In A: [1; 2; 5; 10]

What Have You Tried So Far?

Also I Have To Ask, Is The Next Number In A 17?

@madhan: I assume your code is the solution. Please post it as answer.

@Jan: Done :-)

Actually matrix c should be made by taking max. values from A and adding with it the corresponding element in B ( ie. if a(12) and a(13) are the max velues of A then add b(12) with a(12) and b(13) with a(13))

The new column matrix is [ a(12)+b(12)

a(13)+b(13)]

[madhan ravi]

You say max but why do you say a(12) & a(13) , completely vague and unclear. See if maxk() does your job.

Answer 1

[madhan ravi]

[Value,Index]=max(A+B)

Answer 2

A bold guess:

index = (A == max(A));
A(index) + B(index)
