choosing function in array problem

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

What is your input in terms of Matlab variables, and what is the output you want in terms of Matlab variables? It sounds like it will be fairly easy to solve your problem, but currently it is not clear enough for me what your actual problem is.

Thanks for the comment, @Rik

it is just from my calculation i've taken the biggest value at 'Absol-Val' row, which is 3.4 . so i want to take the value all above like this

Number    4
Pos      11
Value   -3.4

how to take this data:

• separately?
• and also, combined?

because when i use function " max( : ,4)" , it is just get the value of it, and because of that i have to take data value above it

sorry for my bad english, i hope you get the idea about this problem

Edit1#

since the data we get from function " max( : ,4)" where it placed at cell (4 , 4) . so how to make this "automatically" take the value at cell (3,4) and cell (2,4)? what function do we have to use?

thanks,

Hawariyan

What Rik is asking is, what is your data format?

Is it numeric? If so, all in one array

mat=[1       2       3       4       5
     7       8       9       11      15
     0.8     1.5     3      -3.4     2
     0.8     1.5     3       3.4     2]

Or individual variables?

Number    =  [1       2       3       4       5]
Pos       =  [7       8       9       11      15]
Value     =   [0.8     1.5     3      -3.4     2]
Absol_Val =   [0.8     1.5     3       3.4     2]

Or is the data in a table? or a cell array?

[Rik]

You don't show your Matlab variables (neither input nor output). Without it I cannot provide you with adequate help.

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:

Edit1#

data in MATLAB is simplified like this

Table = [   1       2       3       4       5;
            7       8       9       11      15;
            0.8     1.5     3      -3.4     2;
            0.8     1.5     3       3.4     2;]
choose_abs_tab = max(Table(4,:))
% 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

Really apriciated for helping me, much love

Thanks a lot,

[Dyuman Joshi]

Table = [   1       2       3       4       5;
    7       8       9       11      15;
    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

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,

Hawariyan

[Dyuman Joshi]

I can suggest you to go through the MATLAB documentation -

Arrays and Matrices

You can also take the MATLAB Onramp Course
