51.	The input to the evalc command is given using {}.(a) True(b) FalseI got this question during an interview.My enquiry is from Evaluation in chapter MATLAB Programming of MATLAB
Answer» Correct CHOICE is (b) False Explanation: The input ARGUMENT to the evalc COMMAND is given within parentheses. Hence, MATLAB will return an error if we USE {}.

52.	What is common to evalc and the eval commands, apart from the output?(a) The error message is displayed separately(b) The outputs are of different accuracy(c) There is nothing common(d) evalc does not existThe question was posed to me during an interview.This interesting question is from Evaluation topic in portion MATLAB Programming of MATLAB
Answer» Correct CHOICE is (a) The error message is displayed SEPARATELY Explanation: The error messages, if any error, pertaining to the INPUT EXPRESSION, occurs, are displayed separately by both the COMMAND.

53.	The precedence of Transpose operation is ____________(a) after &(b) after \|(c) before .^(d) after ^I had been asked this question during an internship interview.My question comes from Logical Expressions topic in portion MATLAB Programming of MATLAB
Answer» The CORRECT choice is (C) before .^ For explanation: The transpose OPERATION has the highest precedence amongst all the aforementioned operators. The HIERARCHY is .’, .^, ^, &, \|. Hence OPTION before .^ is correct.

54.	Menu-driven architecture should be done by ________(a) if-else structure(b) switch-case structure(c) stack(d) loop structureThe question was posed to me in an international level competition.The above asked question is from Branching topic in portion MATLAB Programming of MATLAB
Answer» The CORRECT answer is (b) switch-case STRUCTURE For EXPLANATION: A Menu implies that we have sections. A switch-case structure offers sections or cases which will be IMPLEMENTED based on the switching value. Hence, this is perfect for a menu-driven architecture.

55.	To enter a value and change the course of working of a function while it is working, we use the __________(a) dbstop(b) db(c) keyboard(d) enterI have been asked this question in an interview for internship.This key question is from Debugging topic in division MATLAB Programming of MATLAB
Answer» Correct answer is (c) KEYBOARD Explanation: The keyboard command is pre-defined in MATLAB and allows us to enter the debugging MODE. We need to give the command in our m.file where we want to start debugging and then the control will RETURN to the keyboard where we will be ABLE to give new value to the parameters INVOLVED in the function.

56.	What does the function all() do?(a) Returns 1 if all elements within it are 0(b) Returns 0 if all elements within it are 0(c) Returns 0 if all elements within it are non-zero(d) Returns 1 if all elements within it are non-zeroThe question was asked in quiz.The query is from Logical Expressions topic in section MATLAB Programming of MATLAB
Answer» Right choice is (d) RETURNS 1 if all elements WITHIN it are non-zero Easiest explanation: The all() function is inbuilt in MATLAB. If we give a VECTOR INPUT to our function, it will return a 1 if all the elements of the vector are non-zero.
