A growing number of people are becoming more health conscious watching their diet and exercising more. Statistics are available to help them monitor their progress toward becoming a healthier person. The body mass index (BMI) is a statistical measure which compares a person’s weight and height. Though it does not actually measure the percentage of body fat, it is used to estimate a healthy body weight. The following equation is used to calculate body mass index. Note: The mass is the body weight in kilograms and height is in meters. [http://en.wikipedia.org/wiki/Body_mass_index]
You have discovered equations to calculate the Ideal Body Weight (IBW) and want to add this feature to your program. The following equations are used to compute the IBW, where height is in inches and the IBW is in kilograms. The user will need to specify the gender by entering a character notation, 1 or 2.
IBW (men) = 50.0 + 2.3 * (height – 60) IBW (women) = 45.5 + 2.3 * (height – 60)

Include the follow comments at the beginning of this (and ALL) files.
% program file name, ex. assign02a.m ALL STUDENTS’ NAMES MUST MATCH NAMES ON CANVAS. % due date of the assignment
% a short narrative about what the file does
MODIFY narrative to include current requirements.
Use the algorithm given as comments throughout your program.
Observe the instructor’s rule for naming variables. o Use ALL CAPS for constants variable names.
o Start other variables with lower case. o Use descriptive variable names.
Use Sample Input/Output as a guide. Code clarity:
o Indent blocks as needed. Use Smart Indent.
o Divide your solution program code into sections as noted in thealgorithm.
Use blank lines as needed to group statements.
o Use section comments as well as the algorithm step comments.
o Remove statements from previous assignments that do not apply tothe
current requirements.
Use comments to show units.
Use the CONSTANT and variable names; not numbers. Exceptions are incrementers and numbers withoutidentity. No extra output, i.e. use semicolons

Program: assign03a.m
You are to write a program (a MATLAB script file) that prompts the user to enter a weight in pounds and a height in inches (1 kilogram = 2.2046 pounds, 1 inch = 2.54 centimeters). Using the algorithm and sample output as a guide, to get the data, determine the BMI and IBW; and display the BMI, BMI category, and Ideal Body Weight for the user-entered gender. Because people make mistakes, all data needs to be validated as correct before using it.
Additional Problem Constants: (with units) None.
Additional Problem Inputs: (with units) gender
Additional Problem Outputs: (with units) IBW in pounds
Additional Other variables: (with units) as needed
Equations:
See above and previous assignments. Algorithm: Use as comments below.
See below.
Sample run output:
Test with bad and good data.
Enter the height in inches(59-78): 58
Enter the height in inches(59-78): 79
Enter the height in inches(59-78): 72
Enter the weight in pounds(90-350): 85
Enter the weight in pounds(90-350): 355
Enter the weight in pounds(90-350): 165
Is the person a female(1) or male(2)? Enter 1 or 2: 5 Is the person a female(1) or male(2)? Enter 1 or 2: 2
