MATLAB: How to do foward right division

right division

I have an array of A (1×182) and B (1×182). When I use C=A/B; it gives one single number. How did Matlab get that single number?

I understand if I use ./ I will get C=(1×182).

The / operator ( mrdivide) is particular to matlab. It solves a system of linear equations. In your particular case, it finds x such that x*B = A (note the reversal of the order of A and B) using the least square method, so it basically performs a linear fit between A and B with the added constraint that the line goes through the origin.

The traditional division is always ./ ( rdivide)

If your data are column vectors x and y and your model is

y=m*x+b

then the solution for b would simply be

b_fit = mean(y-m*x);

MATLAB: Data of two column matrix .(A&B) extract corresponding elements from B ,according to some conditions in A.and add that elements and give a single element according to the conditions

A= [1 5 10 5 2 12];
B= [10 30 30 40 50 60 ] ;
sum(B(A<4))
sum(B(A >4 & A<9))
sum(B(A>9))
