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

This problem will yield a standard formula given in elementary statistics for a least squares line, making use of the normal equations. (a) Given pairs of data points (x1, Y1), (x2, Y2), ..., (xn, Yn) consider approximating lines of the form y = mx+b. The error e; for the ith pair is the distance between y; and the height (y value) of the line at xi. This is ei = Yi — (mxi + b).

The plane through the origin in R³ given by ax+by+cz = 0 for real numbers a, b, c, is the set of all points (viewed as vectors) orthogonal to the normal n = (a, b, c) to the plane. To find the distance from a point w (xo, Yo, zo) to the plane ax+by+cz = 0 we can find the projection of w onto the normal ñ and then find the length of this projection. Do this to derive a generic formula for the distance in terms of xo, Yo, Zo, a, b, c. First find the length squared and then take a root. b) To find the distance from a point w (xo, Yo, zo) to a plane ax + by + cz = d, not necessarily not through the origin, one approach is to shift all z coordinates down by d. That is, replace (x, y, z) by (x, y, z — d). The relationship between the plane and w is unchanged so we can find the distance by finding the distance between (xo, Yo, zo - d) and the plane ax + by+cz = 0 through the origin.
