need solution of exercice

[Adam Danz]

I (unfortunately) don't speak the language in the text. But even if I did speak that language, there's no way I would put more time into the answer than the time put into making the question.

At the very least, type out the question so people can read it and be specific about the help you need.

(First exercise involves calculating the sum of two matrices, and the product of two matrices. if, while and for must be used in the code.

Second exercise involves recursive calculation of maximum and minimum of two vectors.)

Ask

[KHAIF HICHEM]

yes , its about

"(First exercise involves calculating the sum of two matrices, and the product of two matrices. if, while and for must be used in the code.

Second exercise involves recursive calculation of maximum and minimum of two vectors.)"

But i need the solution of there (the script to do this exercise)

What have you tried so far?

[KHAIF HICHEM]

sir please this is home work

i have trying this

the sum:

for i = 1:n
 for j = 1:m 
C(i,j) = A(i,j) + B(i,j);
 end 
end 

and in the multi :

for i = 1:n 
for j = 1:n 
x = 0 
for k = 1:n
 x = x + A(i,k)*B(k,j);
 end 
C(i,j) = x
 end
 end 

but i dont now where is ther problem in this

Second exercise involves recursive calculation of maximum and minimum of two vectors.)

[KHAIF HICHEM]

and in the second exercise i have trying this

function [ vmin ] = mini(vect) 
%MINI retourne le minimum d’un vecteur
 n = numel(vect); if n == 0, vmin = []; else vmin = vect(1);
 for k = 2:n
 if vect(k) < vmin, vmin = vect(k);
 end 
end
 end
 function [ vmax ] = maxi(vect)
 %MAXI retourne le maxiimum d’un vecteur
 n = numel(vect);
 if n == 0, vmax = []; else vmax = vect(1);
 for k = 2:n
 if vect(k) > vmax, vmax = vect(k); 
end 
end
 end  

but the same problem can't resolve

[Walter Roberson]

what problem are you observing ?

[Moussa Attati]

function y = ProductFun(a,b)
    m  = size(a,1) ;    % Column
    n = size(b,2) ;    % Rows
    if  size(a,2)==size(b,1) 
        y = zeros(n,m);
        for i = 1 : m
            for j = 1 : n  
                y(i,j)= a(i,:)*b(:,j) ;   
            end
        end
    else
        disp(' The matrice do not have the same size ')
    end
end

function y = SumFun(a,b)
    k = size(a,1) ;    % Line
    j  = size(a,2) ;    % Column
    if size(a) == size(b)
        y = zeros(k,j) ;
        for i = 1 : k
            for u = 1 : j  
                y(i,u) = a(i,u)*b(i,u) ;

    else
        disp(' The matrice do not have the same size ')
