In this case i want to / already take(n) the biggest Absol-value, because of that i have to process the number in 'Pos' and 'Value', sequentially 11 and -3.4. what i want to ask is:
  • what function did i have to use to take value of 'Pos' and 'Value' separately and combined ? so far i just learn about max/min and other functions but it's only dscribe itself and not other data
  • could you give me the example of this with value of 'Value' and 'Pos' separately and combined taken? thanks alot for this to help my study in make thesis :)
much love
data in MATLAB is simplified like this
Table = [ 1 2 3 4 5; %Number
7 8 9 11 15; %Pos
0.8 1.5 3 -3.4 2; %Value
0.8 1.5 3 3.4 2;] %Absol-value
Table = 4×5
1.0000 2.0000 3.0000 4.0000 5.0000 7.0000 8.0000 9.0000 11.0000 15.0000 0.8000 1.5000 3.0000 -3.4000 2.0000 0.8000 1.5000 3.0000 3.4000 2.0000
choose_abs_tab = max(Table(4,:))
choose_abs_tab = 3.4000
% we get the value of choose_abs_tab is at cell (4 , 4)
%after this step i want to take data at cell (3,4) and cell(2,4)
%problem asked is what i write it

thanks for the comment, @Dyuman Joshi
both seems fine, and i've already updated the table the problem with a single table to make easier to read which is like this too:

0.8 1.5 3 -3.4 2;
0.8 1.5 3 3.4 2;];
[maxabsval,maxid] = max(Table(4,:)) %this will get the first index of maximum value in the row
maxabsval = 3.4000
maxid = 4
Separate
pos=Table(2,maxid)
pos = 11
val=Table(3,maxid)
val = -3.4000
Together
valpos=Table(2:3,maxid)
valpos = 2×1
11.0000 -3.4000

I can suggest you to go through the MATLAB documentation -
Arrays and Matrices
You can also take the MATLAB Onramp Course
