Computer Methods in Chemical Engineering 2ndEdition SOLUTION MANUAL by Nayef Ghasem
What will the statement "myNum = 2 + 2" store in myNum? - ANSWER: 4
Suppose you want to automatically generate a vector of with 2 entries; the 1st entry
starting at 0 and ends at 1. How would you create this vector in MATLAB? - ANSWER:
x = linspace(0,1,2)
Whats another way to do this? - ANSWER: 0:1:2
Now Suppose you want to automatically generate a vector of 11 entries; the 1st
entry starting at 0 and ends at 1. How would you create this vector in MATLAB? -
ANSWER: x = linspace(0,1,11)
Whats another way to do this? - ANSWER: 0:1:11
Now Suppose you want to automatically generate a vector with 8 entries; the 1st
entry starting at 0 and ends at 3. How would you create this vector in MATLAB? -
ANSWER: x = linspace(0,3,8) or x = 0:3:8
How would you access the first twelve elements for y? - ANSWER: y = (1:12);
x(1:12)
OR
y = (1:12);
x(1:12)
How would you access the 1st four multiples of 3 specified in a vector? - ANSWER:
y([3 6 9 12])
Write a statement transposing x - ANSWER: x'
Write two statements that notes the difference in tranpose of z - ANSWER: z' and z.'
Elementary functions in MATLAB
Use the following few commands (a script) to make a plot. The evaluation of
v=cos(u) creates a vector whose elements are:
v(k) = cos(u(k)) where k = 1, 2, ...n - ANSWER: n = anu number;
u = linspace(0, 2*pi*n);
v = cos(u);
plot(u,v)
, How would you clean up this plot? - ANSWER: By plotting axis label and a title; the
text inside the single quotes is a string which we intend to be the labels.
xlabel('u');
ylabel('v');
title('v = cos(u)');
command "help plot" would be very helpful
Write a statement that would transpose a 3x4 matrix - ANSWER: x = [1 2 3 4; 5 6 7 8;
9 10 11 12];

If the previously-entered statement was "num1 = 5", what value will be stored in
num2 after the statements "num1 = num1 + num1" followed by "num2 = num1 + 3".
- ANSWER: 13;;
The interpreter computes 5 + 5, which is 10, then stores 10 in num1. The interpreter
then computes num1 + 3, which is 10 + 3 or 13, and stores 13 in num2.
If the previously-entered statement was "num1 = 9", what value will be stored in
num2 after the statement "num2 = num1 * num1"? - ANSWER: 81
If all previous statements dealt only with num1, num2, and num3, what value will
the statement "num4" print? - ANSWER: error
If all previous statements dealt only with num1, num2, and num3, what value will
the statement "num4" print? - ANSWER: error
What symbol at the end of a statement suppresses printing of the result? -
ANSWER: ; (semicolon)
