Hello everybody.
A=[1,2,3,4,5,6,7,8,9,10;1,2,3,4,5,6,7,8,9,10;1,2,3,4,5,6,7,8,9,10;] % not a fixed size, can be build with n*5
How can I build the sum of five numbers? I don´t know which algorithm or function to use, if the length of the matrix is unknown(rows are multiple times 5 and normally the numbers are randomnly generated).
B=[15,40;15,40;15,40] % wanted output
Can you help me putting this operation into a for loop, so that I can do it on every size of the matrix?
Thanks.

n=input('Enter number of rows:');
A=rand(n,10);
B=zeros(n,2);
for x=1:n
B(x,1)=sum(A(x,1:5));
B(x,2)=sum(A(x,6:10));
end
display('The required matrix is:')
B
