MATLAB EXAM WITH COMPLETE
SOLUTIONS LATEST UPDATE
(2025/2026 ) – JUST RELEASED
1. abstraction - ANSWER ✓ the evolution of computer
language is driven by a process ___________.
2. interpreter - ANSWER ✓ will directly read a high-level
statement written in the programming language,
execute the operation specified by that statement, then
read the next statement, and so on.
3. array - ANSWER ✓ a matrix is a rectangular array of
items in rows and columns; is an ordered sequence of
items of a given data type
4. size - ANSWER ✓ row x column
5. double colon operator - ANSWER ✓ constructs a
numeric row array by specifying a starting value, an
, increment value, and a terminating value, with those
values separated by colons.
6. Ex: myArray = [5:1:9] yields array [5, 6, 7, 8, 9].
7. 1x0 - ANSWER ✓ What size is the row array created
by [4:-2:5]? Type the size as: NxM
8. MATLAB was developed in the late 1950's - ANSWER
✓ False - 1970
9. MATLAB is a high-level language that excels at
creating exceptionally fast-executing programs -
ANSWER ✓ False - it supports scientific and
engineering computations
10. clc - ANSWER ✓ Clears the command window. Does
not affect the workspace, meaning variables are
unchanged
,11. clear - ANSWER ✓ clears all variables from the
workspace, so all variable values are lost.
12. diary - ANSWER ✓ Records into a file almost
everything that appears in the command window. The
file's name is chosen by programmer, such as "my
session.txt". "diary off" ends the recording
13. exit - ANSWER ✓ exits the MATLAB session
14. who - ANSWER ✓ Prints all variables in the current
workspace
15. whos - ANSWER ✓ Prints all variables in the current
workspace as well as some extra information about
their size, bytes, class, etc
16. ctrl-c - ANSWER ✓ While not a MATLAB
command, this keystroke sequence interrupts an endless
MATLAB calculation that a programmer may have
entered accidentally. Afterwards, the programmer can
enter a new command.
, 17. assignment statement - ANSWER ✓ such as age =
20; upon being executed, writes the current value of the
item on the ='s right side into the variable on the ='s left
side.
18. assignment operator - ANSWER ✓ The '=' is kn own
as the ______.
19. identifier - ANSWER ✓ A variable's name is called
an ______.
20. keywords - ANSWER ✓ break, else, global, return,
case, else if, if, epode,catch, end, otherwise, switch,
classdef, for, parlor, try, continue, function, persistent,
while
21. numeric variable - ANSWER ✓ stores a number
22. integer number - ANSWER ✓ positive or negative
number that does not have a fractional part
