Hi guys, I m italian (excuse me for my english) and I have a question about sprintf (disp,..):

My code is :

for k=1:1:Matrice_Gruppi(1, end)      
    c1={nomi_famiglie};      
    c2={Matrice_Gruppi(5, k)};      
    sprintf('\n %s paga %s euro.',c1{1},c2{1});       
end

I simply would

Insert with keybord a string and to save it into nomi_famiglie then
To print values of nomi_famiglie and Matrice_Gruppi on command window (inizially, then I would create a interface).

I see the error:

Undefined function or variable 'sprinf'.

Could you help me please?

Thanks and bye

@Luca Filippone: I think you should be using

for k = 1:numel(Matrice_Gruppi)

There is no function sprinf(). Use sprintf(), with a "t", instead.

Or better yet, don't use cell arrays:

for k=1:1:Matrice_Gruppi(1, end)      
    myStrings{k} = sprintf('%s paga, %f euros.\n',...
        nomi_famiglie, Matrice_Gruppi(5, k));
end  
celldisp(myStrings);

assuming Matrice_Gruppi is an array of doubles, not strings like you implied by using %s.

You showed in your comment above that Matrice_Gruppi is a 5 by 1 array. And Matrice_Gruppi(1,end) = 520.2000. So in your sprintf when you're trying to access Matrice_Gruppi(5, k) when k = 1,2,3,4,5,.....520, will fail because there is no columns beyond 1.
