Explanation: The amount of memory allotted to the Virtual Address Space of MATLAB is given as an array to q. Hence, q is correct.

Explanation: The function handle can be given as an input to the timeit() command. It’s not necessary that we need a separate variable to declare a function handle.

Explanation: The timeit function returns the time in seconds. Hence, the above statement is false.

Explanation: Since x is declared as symbolic, the function sin(x) will only initialize itself as sin(x), It doesn’t compute a specific value and hence the time required for initializing sin(x) as a vector of symbolic elements is correct.

Explanation: The function handle has been declared with an error. A set of parentheses is missing. TH e function handle is defined as @()sin(x). Hence, the above code will give an error.

Explanation: The method of preallocation helps in increasing the performance of memory. It can be used to specifically increase the speed of the operation.

Explanation: The time calculated and assigned to c is usually more than that in a. This is because the cpu time increases in the third statement only. Hence the option, which says that a is not equal to c is correct.

Explanation: There is an error in the above code. The function handle has been wrongly decalred since the ‘@’ is missing. Hence the option, which says there will be an error, is correct.

Explanation: The latter is always greater than the former. This is because the physical memory is getting used up during operations.

Explanation: The command is misspelled. The correct command is tic only. Hence, the above statement is false.
