Split a matrix in two matrix according a criterion

Hello,

I have a text-matrix :

    genotype = 
    'WT'
    'WT'
    ...
    'KO'
    'KO'
    ...
  (format x*1 cell)

And, a number-matrix :

    var =
    60
    80
    ..
    50
    60
    ..
  (format : x*1 double)

It is good for using anova1 :

r = anova1(var, genotype)

But, for further analysis and plotting, i need another format :

wt_ var =
60
80
...

and

ko_var =
50
60
...

How can i generate wt_var and ko_var using genotype and var ?

Thanks !

% sample data
  G = {'wt','wt','ko','ko','wt'}
  V = [10 20 30 40 50]
% transform G into numbers, there are other ways
  [tf, idx] = ismember(G,{'wt','ko'})
% select
  V_wt = V(idx==1) 
  V_ko = V(idx==2)

Thank you for your answer :-) I do not know if i understand, but it seems to not do exactly what i ma looking for.

It is more like this :

genotype = 
    'WT'
    'KO'
    'WT'
    'KO'
var =
    1
    2
    4
    5

Another way to see it :
    'WT' 1
    'KO' 2
    'WT' 4
    'KO' 5
After :
wt_var =
    1
    4

ko_var =
    2
  5
