Question

1. Write a function that will receive two input arguments that is the height in inches (in.) and the weight in pounds (lb) of a person and return two output arguments that is the height in meters (m) and mass in kilograms (kg).

1. Determine in SI units the height and mass of a 5 ft.15 in. person who weight 180 lb.
2. Determine your own height and weight in SI units.

Note: 1 meter = 39.3701 inch, 1 foot = 12 inches, 1 pound = 0.453592 kilogram

Solve this please using MATLAP

Answer 1

Answer:) The code for this function is as follows:

CODE:

%%% Function definition
function [ height_m, weight_kg ] = converter( height_in, weight_lb )
% This function takes the height in inches and weight in pounds as
% inputs, and outputs the height in meters and weight in kilograms

   feet = floor(height_in); % get the number of whole feet
   inches = 100*(height_in - feet); % get the number of inches
   height_m = (feet * 12 + inches) / (39.3701); % convert feet to inches,
                                                % and then convert inches
                                                % to m
   weight_kg = 0.453592 * weight_lb; % use the conversion from pounds to kg
   disp("Weight in kg : ")
   disp(weight_kg)
   disp("Height in m : ")
   disp(height_m)
   return
end

The code looks as follows when typed out in MATLAB:

Suppose we give the input height = 5 ft 15 inches, weight = 180 lb (given as an input which looks like (5.15, 180) ), we get :

>>converter(5.15, 180)
Weight in kg :
81.646559999999994
Height in m :
   1.904998971300556

OUTPUT:

Note: the final 'ans' is just the function returning the first variable's value, and is the same as the height_m variable's value.

Suppose the user's weight is 170 lb, and the user's height is 6 ft 10 inches. This would be :

>> converter(6.10, 170)
Weight in kg :
77.110640000000004
Height in m :
   2.082798875288606
