Question

Question 1 1. Consider the following Matlab program 5 - (2 < 3) & (C2 > 3) 1 (1 - 0)) What is the final value of s? A. True B. *1 CO D. false 2- Which expression tests whether variable x is between (but not the same as) the values 5 and 10 (a) 5 <x< 10 (b) 5 <= x <= 10 (c) 5 < X & X > 10 (d) x < 10 & 5 < x (e) none of these 3. Which of the following is a MATLAB expression for testing "x is outside the range from 3 to 5 (the range includes 3 and 5)? (a) 3 > X & X > 5 (b) 3 > x x < 5 (c) 3 > X x > 5 (d) cannot be expressed in MATLAB (e) none of the above 4- What is the default increment value in a for-loop? a) O b) 1 c) An increment value is necessary d) 0/1 Question 2 ------- Section Break (Next Page) Evaluate relational and logical expressions as Matlab does: (a) 4 <5&6 > 7 (b) (5 = 5) 1 (c) (1&10)

Answer 1

Here's the solution:-

1.B
2.A
3.C
4.B

section break
2.
(a) 4<5 & 6>7
ans = 0

(b)(5=5)|1
parse error:

invalid constant left hand side of assignment

(c)(1 & 1 | 0)
ans = 1

3.>> for i=1:4
a=5
a=a+5
end disp(a)

OUTPUT:-

parse error:

syntax error

>>> end disp(a)

4.(a)>> x=3;
>> while(x<8)
disp('Am I done yet?')
x=x+2.5;
end

OUTPUT:-

Am I done yet?
Am I done yet?

(b)
>> c=0;
>> i=10;
>> while i~=1
c=c+i;
i=i-3;
end

Ans.
The loop will run 3 times

5.
(a)
V~=X
ans =

1 1 1 1

(b)
V==Y
ans = 0

(c)
X+Y/2
ans =

41.500 37.500 38.500 41.500

(d)
X(V~=X)
ans =

7 3 4 7

(e)
Y>7
ans = 1

(f)
Y(Y>7)
ans = 69

6. OUTPUT
>> a
a = 20
>> b
b = 80
>> c
c = 2
>>   

7
(a) No Output since I is less than 5 always, I=1
(b)OUTPUT:-
Move right
