5. Problem 6.15 ***Don't work this problem as it is stated. (Do not do parts a, b, or c.) Instead, for this problem, work a variation of the problem as described below.

Create the primary function celsius_conversions. Create subfunctions as follows:

• F_to_K
• C_to_R
• C_to_F

The primary function celsius_conversions should take a single input 1 x n vector of Celsius temperatures and output a n x 4 matrix where the columns are as follows:

• Column 1: the original input (Celsius)
• Column 2: the input temperatures converted to Fahrenheit
• Column 3: the input temperatures converted to Kelvin
• Column 4: the input temperatures converted to Rankine

Finally, call your primary function from the command window to convert 25 values of Celsius from 0 to 100 into F, K, and R.

2. Problem 10.2. Again, put your explanation in your comments.
3. Problem 10.6. Use Matlab functions to answer the three questions presented. That is, don't manually count sizes or look things up in tables.
4. Look at the solution to #3 for Practice Exercise 10.2 on page 367. Update the code so that it only executes if the first character in the string is lowercase. Assume that only letters will be used as input (no spaces, numbers, or special characters).
5. Modify the code you just created so that in the event that the first character in the string is uppercase, assume all the characters are uppercase and convert them to lowercase. Continue to convert to uppercase if the first character is lowercase. Assume that only letters will be used as input (no spaces, numbers, or special characters).
6. Finally, modify the code you just created so that the code will take a string and convert any lowercase letters to uppercase and any uppercase letters to lowercase. Assume that only letters will be used as input (no spaces, numbers, or special characters).
