function bmi = bmi_calculator(hw)

% Convert the height values from inches to meters
new_height= hw.height*2.54/100;

% Convert the weight values from lbs to kilograms
new_weight=hw.weight/2.2;

% Calculate the bmi for height and weight combination and return the output variable 'bmi'
bmi =new_weight./new_height.^2 ;
end

To test the code on MATLAB, the input hw was used as a table and it runs perfectly on MATLAB. But here it shows that the solution is wrong. Could anybody please explain?

The problem specifies that the input hw is a matrix with two columns (not a table). So, the error is saying that you cannot use dot indexing on a matrix.
