MATLAB: Sum of consecutive elememts

for loop homework

suppose i have a matrix A=[1 2 3 4 5] and i need another matix as sum of consecutive elememts i.e [3 5 7 9] how to do using loop

Best Answer

Without loop:

 res=A(1:end-1)+A(2:end)

With loop:

 for i=1:numel(A)-1
     res(i)=A(i)+A(i+1);
 end

MATLAB: I have a matrix BB = [-1 5 6;4 -3 2;5 6 -7]. How can i print the location(index) of the positive elelments using for loop and using while loop

BB = [-1 5 6;4 -3 2;5 6 -7] ;
[nx,ny] = size(BB) ;
for i = 1:nx
    for j = 1:ny
        if BB(i,j)>0
            fprintf('%d %d %f\n',i,j,BB(i,j))
        end
    end
end

MATLAB: WHILE LOOP program does not work

Try it without loops, in a more MATLAB-ish vectorized way:

indexesToSum = a>=4 & a<=15
Re = sum(a(indexesToSum))
