Introduction to Analytical Programming
Lab Exercise 1
1. Explain what the following MATLAB commands produce, then excute the following expressions in
MATLAB command window.
(a) (3 4) 2
(b) cos(pi)
(c) y= 10 5
(d) x= 5
(e) exp(x)
2. Deﬁne variables a, b, c and das a= 15, b = 4, c = (3 ×a)/b, and d=a×b×c
b+c, then evaluate the
followings in MATLAB command window. (Note: the followings are mathematical expressions).
(a) b×d
a×(c+d)×eb+c
d×log2(a)cos(d×c) + ab
(b) a3+c2
dc+ln(|a+bcd|)
(c) c×d×π(a+b)2
log10 (a×c)
3. Think about what results would be of the following expressions, and then type them in MATLAB to
3 == 5 + 2
'b'<'a'+ 1
10 >5+2
(10 >5) + 2
'c'== 'd'- 1 && 2 <4
'c'== 'd'- 1 || 2>4
xor('c'== 'd'- 1, 2 >4)
xor('c'== 'd'- 1, 2 <4)
10 >5>2
4. Create a row vector vec start from -10 to 10, by incremental 5, using colon operator. The do the
followings:
(a) Create a new vector sub vec by extract the last 3 elements of vector vec.
(b) Change the value of last element of vec such that the value of last element is the function sin of
itself.
