choosing function in array problem

Question

0 个投票

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;];
[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

Hello, Mr @Dyuman Joshi

Thanks for the answer!!

anyways, do you have reccomendation for "cheat sheet" or books about array funtion / other function in MATLAB? thanks

Sincerely,

I can suggest you to go through the MATLAB documentation -

Arrays and Matrices

You can also take the MATLAB Onramp Course
