extracting a particular element from a matrix
显示 更早的评论
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

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.

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

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

A bold guess:
index = (A == max(A));
A(index) + B(index)
