Question

Which of the following statements is true about user-defined MATLAB functions

A. They cannot have parameters
B. They are built-in functions
C. They are case-insensitive
D. They cannot return values

Answer 1

User-defined MATLAB functions can indeed have parameters and return values, are case-sensitive, and are not built-in functions.

Step-by-step explanation:

User-defined MATLAB functions can have parameters and can return values, they are not built-in functions but are case-sensitive. When creating functions in MATLAB, a user can define the function's name, input parameters, and return values. These functions are distinct from built-in ones, as they are created by the users themselves to perform specific calculations or operations that are not covered by MATLAB's standard library. Unlike some programming environments that might be case-insensitive, MATLAB differentiates between uppercase and lowercase letters in function names, making it a case-sensitive language.

For example, a function called CalculateArea is different from calculatearea. This case sensitivity applies to all functions, variable names, and other identifiers in MATLAB. As for parameters and return values, these are essential aspects of MATLAB functions that enable users to pass data into the function and receive results after computation, respectively. By utilizing parameters and return values, MATLAB functions become versatile tools for handling various computational tasks.
