% So you want my phone number and my BMI? How shallow can you get? % Worksheet : Finding the BMI of a person, classifying the BMI and % suggesting a healthy weight % Language : Matlab 2007a % Authors : Autar Kaw % Last Revised : September 27, 2008 % Abstract: Finding the body mass index of a person, classifying their health and recommending a target weight. % In 1998, the federal government developed the body mass index (BMI) % to determine ideal weights. Body mass index is calculated as % 703 times the weight in pounds divided by the square of the height in inches, % the obtained number is then rounded to the nearest whole number % (23.5 will be rounded to 24; 23.1 will be rounded to 23; 23.52 will be rounded to 24). % % Write a MATLAB program to do the following: % % Assign a value to weight in lbs, and height in inches and % then calculate BMI as a rounded integer. % Output a variable called health_id as % 0 if the person's BMI <19 (underweight) % 1 if the person’s BMI is 19?BMI?25 (healthy) % 2 if the person's BMI is 25<BMI?30 (overweight) % 3 if the person’s BMI is >30 (obese) % Output also a variable hw for healthy weight in rounded integer lbs for all the conditions. % Use fprintf command with explanation for the inputs and outputs clc clear all % INPUTS % Weight in lbs weight=180; % Height in inches height=69; %REST OF THE PROGRAM bmi=weight/height^2*703.0; bmi=round(bmi); % Assigning the proper health_id and finding the suggested healthy weight % health_id= BMI category % hw = healthy weight % You can use 4 separate if-end statements or switch case statement also. if (bmi<19) health_id=0; hw=19*height^2/703; elseif (bmi>=19 & bmi<=25); health_id=1; elseif (bmi>25 & bmi<=30); health_id=2; hw=25*height^2/703; else health_id=3; hw=25*height^2/703; end hw=round(hw); % Printing the outputs disp('The BMI MATLAB program') disp('Author: Autar K Kaw') disp('http://numericalmethods.eng.usf.edu') disp('September 28, 2008') disp(' ') fprintf('\nWeight of person =%6.0f lbs',weight) fprintf('\nHeight of person =%6.0f inches',height) fprintf('\nYour BMI is =%g ',bmi) if health_id==0 fprintf('\nYou are underweight. \nYour target weight is =%6.0f lbs',hw) elseif health_id==1 fprintf('\nYou are a healthy weight. \nYour target weight is =%6.0f lbs',hw) elseif health_id==2 fprintf('\nYou are overweight. \nYour target weight is =%6.0f lbs',hw) elseif health_id==3 fprintf('\nYou are obese. \nYour target weight is =%6.0f lbs',hw) end
