Perform the following exercises in MATLAB. Follow the required filenames for each activity. Write a program in Matlab that will allow the user to calculate the body mass index (BMI) in kg/m2 and classify the BMI. The user shall input weight in pounds (lbs) and height in centimeters (cm). After the calculation, the program can be able to determine if it is underweight, normal range, overweight, obese I, and obese II

Perform the following exercises in MATLAB. Follow the required filenames for each activity. Write a program in Matlab that shall determine the number of infants (0-2), children (3-12), teenagers (13-17), adults (18 & above) in a group of people. The user shall input the number of age to classify, then after all the ages are entered, display the number if it is infants, children, teenagers, and adults.
7. MATLAB returns the current value of a variable when its name is entered at the command prompt. TASK m was used to compute y. Was y updated when m changed? At the command prompt, type just y. (and press Enter).
In a function file, the input() function - to gather user input from the command window - should essentially never be used. In Matlab Explain that statement, and support your reasoning.
6- Write a script that will prompt the user for a keyword in MATLAB, error-checking until a keyword is entered. Hint: use iskeyword() function.
Please write the answers to the following questions as comments in your MATLAB file. a) What is a syntax error? Give an example as a comment (do not copy the one from the slides). b) What is a logical error? Give an example as a comment (do not copy the one from the slides). c) What is a runtime error? Give an example as a comment (do not copy the one from the slides). d) Explain how debugging works. Explain how the disp() function and breakpoints are used in de-bugging. e) What is the difference between clc and clear?
Perform the following exercises in MATLAB. Follow the required filenames for each activity. Create a pseudo-code/flowchart* and program for the problems below: 1. Write a program that will calculate the area and volume of a cylinder when the radius and height are unknown. The program will ask the user to enter radius (r) and height (h) then calls a local function to calculate the area (A) and volume (V). Display the result of the calculation. Use the formula below for the area and volume. Save program as LE9-1.m and flowchart/pseudo-code as LE9-1.png or LE9-1.txt. A=2πrh+2πr2A=2πrh+2πr2V=πr2h 3. Write a program that will calculate the final velocity and time of travel of a baseball that is thrown downward from a tower of a certain height and initial speed. The program will ask the user to enter height (h) and initial velocity (vo). Create two (2) function files: 1) to calculate the final velocity (v) and 2) calculate the time of travel (t). Display the result of the…
