Answer to Problem 2.1P

Solution:

The output of the following sequence of statements and expressions:

“pvec = 3:2:10”, “pvec(2) = 15” “pvec(7) = 33”, “pvec([2:4 7])”, “linspace(5, 11, 3)”, and “logspace(2, 4, 3)” are “pvec = 3 5 7 9”, “pvec = 3 15 7 9 0 0 33”, “ans = 15 7 9 33”, “ans = 5 8 11”, and “ans = 100 1000 10000” respectively.

Explanation of Solution

Consider the following statement,

pvec = 3:2:10

The statement will generate the sequence of number from 3 to 10 in increment of 2.

So, the output is “pvec = 3 5 7 9”.

Consider the following statement,

pvec(2) = 15

The expression replaces the second term of the sequence of “pvec” with “15” and then displays sequence.

So, the output is “pvec = 3 15 7 9”.

Consider the following statement,

pvec(7) = 33

The expression replaces the seventh term of the sequence of “pvec” with “33” and then displays sequence. Since, the values of the 5th and the 6th terms are not allotted, so these terms are allotted with zero.

So, the output is “pvec = 3 15 7 9 0 0 33”.

Consider the following statement,

pvec([2:4 7])

The expression displays the values placed 2nd to 4th and then 7th from the sequence.

So, the output is “ans = 15 7 9 33”.

Consider the following statement,

linspace(5, 11, 3)

The expression generates three values that are equally spaced from 5 to 11.

So, the output is “ans = 5 8 11”.

And, consider the following statement,

logspace(2, 4, 3)

The expression generates three values that are equal to 10n, here n=2,3,4.

So, the output is “ans = 100 1000 10000”.

% Define the instruction in which the expression replaces the second term of the sequence of “pvec” with “15” and then displays sequence.

pvec(7) = 33

% Define the instruction in which the expression replaces the seventh term of the sequence of “pvec” with “33” and then displays sequence. Since, the values of the 5th and the 6th terms are not allotted, so these terms are allotted with zero.

pvec([2:4 7])

% Define the instruction in which the expression displays the values placed 2nd to 4th and then 7th from the sequence.

linspace(5, 11, 3)

% Define the instruction in which the expression generates three values that are equally spaced from 5 to 11.

logspace(2, 4, 3)
