BY USING MATLAB ONLY.

Problem:

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 persons 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)

Instructions for all assignments scripts:

See Standards for Documentation of MATLAB Programs on the Canvas Resources page.

Insert comments at the top and throughout each file.

o Include the follow comments at the beginning of this (and ALL) files.

% submitters name, GROUP #

% other group members names

% program file name, ex. assign02a.m

% due date of the assignment

% statement about collaboration

% a short narrative about what the file does

o Use the algorithm given as comments throughout your program.

Observe the instructors 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 the algorithm. 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 to the current requirements.

Use comments to show units.

Use the CONSTANT and variable names; not numbers. Exceptions are incrementers and numbers without identity.

No extra output, i.e. use semicolons

Program: assign04a.m

Save your assign03a.m as assign04a.m. Modify the script for the new requirements. 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.
