Formula result won't return a vector as exepected
显示 更早的评论
Hello,
In a simple home exercise we were given a formula which needs to be executed in two different scenarios.
1. In the first scenario, our L is a vector.
R = 22;
L = [100:20:300]
N=1;
X = (L*N)/(R+N)
X returns a vector with the correct numbers.
2. In the second scenario, I was meant to create N as a vector with the command N = [1:3:45].
R=22
L = 300
N = [1:3:45]
X = (L*N)/(R+N)
Now X only returns one single value, 161.9772, which I am not even sure where did it come from. So, please advise me what's wrong with my code.

X = (L*N) ./ (R+N)

Your original code has a vector / a scalar. The operation of the / operator happens to be the same as the ./ operator when the denominator is a scalar.
Your second version of the code has a vector in the denominator. The / operator is different from the ./ operator when the denominator is not a scalar.
