I have a matrix A=[1 0 3 0 0; 0 1 0 1 0]; I have B=sum(A); B=[1 1 3 1 0]; After performing some operation on this matrix B let my matrix B is B=[0.1 0.1 0.25 0.1 0], How can I get back A=[0.1 0 0.25 0 0; 0 0.1 0 0.1 0]. Note: This operation can only be performed on Matrix B. Can anybody help? Thanks in advance

Have you seen what you posted? It is unreadable. Select the code you have in your comment and click the {}Code button.
And if you have working code, what is your question?

I solved it Thank you so much Rik Wisselink
Q=20;
Kr=2;
Kt=3;
A=[10 0 0 ; 0 22 0];
B=sum(A);
if (sum(B(1,:)) > Q)
sorted_matrix = sort(B(1,:),'descend');
N_tilde = size(sorted_matrix,2);
sorted_matrix(end+1) = -Inf;
while(N_tilde > 0)
if ((sorted_matrix(N_tilde) > sorted_matrix(N_tilde+1)) && ...
(sorted_matrix(N_tilde) > (sum(sorted_matrix(1:N_tilde))-Q)/N_tilde))
mu = (sum(sorted_matrix(1:N_tilde))-Q)/N_tilde;
B(1,:) = max(B(1,:) - mu, 0);
break;
else
N_tilde = N_tilde - 1;
end
end
end
A_temp=zeros(Kr,Kt);
for row=1:Kr
for col=1:Kt
if A(row,col)>0
A_temp(row,col)=1;
else
A_temp(row,col)=A(row,col);
end
end
end
A_final=zeros(Kr,Kt);
for r=1:Kr
A_final(r,:)=A_temp(r,:).*B;
end

Rik Wisselink when I asked the Question, I was struggling with the code. Now it's working fine. Thanks
