A.
Check whether the given function name or program is valid or invalid.
Answer to Problem 1ICA
The function name 2b_solved.m is invalid.
Explanation of Solution
Rules for naming MATLAB program/function.
- 1. Name of MATLAB function must start with a letter (alphabet).
- 2. The initial letter must be followed by letters, numbers or underscore.
- 3. The name of MATLAB function must not resemble any reserved words in MATLAB.
The given name 2b_solved.m is started with a number not with a letter. Therefore, the given function name is invalid.
Conclusion:
Therefore, the function name 2b_solved.m is invalid.
B.
Check whether the given function name or program is valid or invalid.
Answer to Problem 1ICA
The function name calc_circum.m is valid.
Explanation of Solution
The given function name calc_circum.m meets all the criteria of rules that have to be followed for proper function name. Therefore, the given function name is valid.
Conclusion:
Therefore, the function name calc_circum.m is valid.
C.
Check whether the given function name or program is valid or invalid.
Answer to Problem 1ICA
The function name graph-data.m is invalid.
Explanation of Solution
Rules for naming MATLAB program/function.
- 1. Name of MATLAB function must start with a letter (alphabet).
- 2. The initial letter must be followed by letters, numbers or underscore.
- 3. The name of MATLAB function must not resemble any reserved words in MATLAB.
The given function name graph-data.m contains hyphen (which is not allowed) not an underscore. Hence, the given function name is invalid.
Conclusion:
Therefore, the function name graph-data.m is invalid.
D.
Check whether the given function name or program is valid or invalid.

Conclusion:
Therefore, the function name help4me.m is valid.
E.
Check whether the given function name or program is valid or invalid.
Answer to Problem 1ICA
The function name MATLAB is fun.m is invalid.
Explanation of Solution
Rules for naming MATLAB program/function.
- 1. Name of MATLAB function must start with a letter (alphabet).
- 2. The initial letter must be followed by letters, numbers or underscore.
- 3. The name of MATLAB function must not resemble any reserved words in MATLAB.
The given function name MATLAB is fun.m contain spacing between the words, which is not allowed. Hence, the given function name is invalid.
Conclusion:
Therefore, the function name MATLAB is fun.m is invalid.
F.
Check whether the given function name or program is valid or invalid.
Answer to Problem 1ICA
The function name matrix*matrix.m is invalid.
Explanation of Solution
Rules for naming MATLAB program/function.
- 1. Name of MATLAB function must start with a letter (alphabet).
- 2. The initial letter must be followed by letters, numbers or underscore.
- 3. The name of MATLAB function must not resemble any reserved words in MATLAB.
- 4. The name of MATLAB function should not contain any special characters like *, #, $ etc. and spacing between the words.
The given function name matrix*matrix.m contains a special character “*” which is not allowed. Hence, the given function name is invalid.
Conclusion:
Therefore, the function name matrix*matrix.m is invalid.
G.
Check whether the given function name or program is valid or invalid.
Answer to Problem 1ICA
The function name Mult2#s.m is invalid.
Explanation of Solution
Rules for naming MATLAB program/function.
- 1. Name of MATLAB function must start with a letter (alphabet).
- 2. The initial letter must be followed by letters, numbers or underscore.
- 3. The name of MATLAB function must not resemble any reserved words in MATLAB.
- 4. The name of MATLAB function should not contain any special characters like *, #, $ etc. and spacing between the words.
The given function name Mult2#s.m contains a special character “#” which is not allowed. Hence, the given function name is invalid.
Conclusion:
Therefore, the function name Mult2#s.m is invalid.
H.
Check whether the given function name or program is valid or invalid.
Answer to Problem 1ICA
The function name pi.m is invalid.
Explanation of Solution
The given function name pi.m meets all the criteria of rules that have to be followed for proper function name. Even though pi.m meets all the criteria, it’s a built-in MATLAB function, which provides the standard value as 3.14. So, it is necessary to avoid the file names, which are same as the name of standard built-in functions.
Conclusion:
Therefore, the function name pi.m is invalid.
I.
Check whether the given function name or program is valid or invalid.
Answer to Problem 1ICA
The function name ReadFile.m is valid.
Explanation of Solution
The given function name ReadFile.m meets all the criteria of rules that have to be followed for proper function name. Therefore, the given function name is valid.
Conclusion:
Therefore, the function name ReadFile.m is valid.
J.
Check whether the given function name or program is valid or invalid.
Answer to Problem 1ICA
The function name SuperCaliFragiListicExpiAliDocious.m is valid.
Explanation of Solution
The given function name SuperCaliFragiListicExpiAliDocious.m meets all the criteria of rules that have to be followed for proper function name. Therefore, the given function name is valid.
Conclusion:
Therefore, the function name SuperCaliFragiListicExpiAliDocious.m is valid.
