I'm trying to display a 2D table

Hi,

i'm trying to display a 2d table for a school projet, and i'm having trouble making it work, the code seem fine to me but I can't see to find how do I call the specific case I want to display.

my code is :

for ii=1:taille

if(ii==1)

fprintf('\t%g\t\t\t\t',tableau(ii));

elseif(ii==2)

fprintf('%g\t\t\t\t',tableau(ii));

elseif(ii==3)

fprintf('%g\t\t\t\t',tableau(ii));

elseif(ii==4)

fprintf('%g\t\t\t\t\t\t\n',tableau(ii));

end

end

fprintf('\n');

fprintf('\n');

%affichage de la deuxième ligne du tableau 2D

for jj=1:taille

if(jj==1)

fprintf('\t%g\t\t\t\t',tableau(jj));

elseif(jj==2)

fprintf('%g\t\t\t\t',tableau(jj));

elseif(jj==3)

fprintf('%g\t\t\t\t',tableau(jj));

elseif(jj==4)

fprintf('%g\t\t\t\t\t\t\n',tableau(jj));

end

end

and the table displays this when i call : afficher_ecran_de_jeu([1,2,3,4;5,6,7,8])

Carte 1 Carte 2 Carte 3 Carte 4

--------- --------- --------- ---------

1 5 2 6

1 5 2 6

when it supposed to display

1 2 3 4

5 6 7 8

thank you in advance. (PS: I started learning MATlab only 4 weeks ago).

To read the rows and columns of a two dimensional table you need to use two indices:

In your example:

tableau(1,1) == 1

tableau(1,2) == 2

tableau(1,3) == 3

tableau(1,4) == 4

tableau(2,1) == 5

tableau(2,2) == 6

tableau(2,3) == 7

tableau(2,4) == 8

When you only use one index, MATLAB defaults to the row first data order in order to convert to a one dimensional vector, so you get 1, 5, 2, 6, 3, 7, 4, 8.
