Textbook Question
Chapter 16, Problem 1ICA
Which of the following are not valid MATLAB variable names? Circle all that apply. For those that are invalid, state why.
Expert Solution & Answer
To determine
Identify the valid MATLAB variables from the given variables and explain the reason for not valid variables.
Answer to Problem 1ICA
The valid and invalid MATLAB variables are identified and explained the reason for invalid MATLAB variables.
Explanation of Solution
Description:
- a. BigNum.docx: The MATLAB variable BigNum.docx is invalid variable since it contains the special character “.”.
- b. Six_Vals: The MATLAB variable Six_Vals is a valid variable since it obeys the naming rules of the MATLAB.
- c. This is a very long MATLAB variable name: As the variable contain the space, the MATLAB variable is not a valid one.
- d. 2BR02B: The variable cannot begin with the number. As the variable begins with the number 2, the variable 2BR02B is an invalid one.
- e. Is_This_Valid?: As the variable contains the special character “?”, the variable is an invalid variable.
- f. Rocket=Space+100;: As the variable contains the special characters “=”, and “;”, the variable is an invalid variable.
- g. Mult2: The variable is a valid one.
- h. log: As the variable log is a name of common function, the variable is an invalid variable.
- i. GClefSign: The MATLAB variable GClefSign is a valid one.
- j. AbcDEFGHijKLmnopqrstuvWXyz_Has_Lots_of_Characters: The variable is a valid one.
- k. DoNotPassGo_DoNotCollect$200: As the variable contains the special character “$”, the variable is an invalid variable.
Conclusion:
Thus, the valid and invalid MATLAB variables are identified and explained the reason for invalid MATLAB variables.

- using MATLABarrow_forwardUSE MATLAB AND SOLVE THIS QUESTION The ideal gas law relates the pressure P, volume V, absolute temperature T, and amount of gas n. The law is P = nRT/ V where R is the gas constant. An engineer must design a large natural gas storage tank to be expandable to maintain the pressure constant at 2.2 atm. In December when the temperature is 4°F (- 15°C), the volume of gas in the tank is 28 500 ft3 . What will the volume of the same quantity of gas be in July when the temperature is 88°F (31°C)?
