%Write a Matlab script to create random integer matrix with elements between -30 and 30.
%The size of the matrix must be first be read from user input. Use loops to sum of each row.
%Then find the differences between all pairs of these sums.
a=input('Enter the size of rows:');
b=input('Enter the size of columns:');
A=randi([-30 30],a,b)
r=zeros(a);
d=zeros(a);
for i=1:a
for j=1:b
r(i)=r(i)+A(i,j);
end
end
for k=1:a
for l=1:a
d(k,l)=(r(k)-r(l));
end
end
difference=triu(d,1)
%So I write this code and it worked -with a problem-. Let's say I created a 2x2 Matrix.
%TheSumOfFirstRow=2, TheSumOfSecondRow=3. As the result I wanna see both 2-3=-1 and 3-2=1.
%But the code that I wrote calculates just 2-3=-1.
Can someone please help :)
