MATLAB: My function isn’t returning an array for an answer with an input array

Question

function [bodyMassIndex] = CalculateBMI(massKg, heightCm)
% Define a function CalculateBMI
% Input:   massKg: Mass in kg
%          heightCm: Height in cm
% Output:  bodyMassIndex: Resulting BMI given mass and height
heightCm = heightCm / 100;
heightCm = nthroot(heightCm, 1/2);
bodyMassIndex= massKg / heightCm;
end

CalculateBMI([75, 90, 118], [178, 180, 200])

Answer 1

bodyMassIndex= massKg ./ heightCm;

The operator you used, /, is about the same as if you had written

bodyMassIndex= massKg * pinv(heightCm);
