et je voudrais chercher le min de quelques colonnes ,aidez-moi svp

[Invité]

Bonjour,

Il faut pour cela convertir tes colonnes en tableaux numériques avec la fonction cell2mat :
Exemple pour la première colonne :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

min( cell2mat(c(:,1)) )

[LEGOLAS19]

nnn je cherche a trouver le min entre les colonnes par exemple entre la colonne c(:,2) et c(:,5)

[Invité]

Le principe reste le même

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
min( cell2mat(c(:,2)), cell2mat(c(:,5)) )
% ou :
min( cell2mat(c(:,[2 5])), [], 2)
