The number in parenthesis at the beginning of each exercise indicates the degree of
skill and amount of effort necessary to complete the exercise. See § 1.4 on page 10
for a description of the rating system.
1. (1) Write the MATLAB statements to create the following:
(a) a row vector t = [0, /4, n/2, 37/4, Jr ].
a row vector u — [0, л/100, 2л/100, ... 99л/100, л].
(c) a column vector v = [sin(0) - cos(0), sin(7/100) - cos(7/100), ... sin(7) -
cos(7)]7
2. (1) Let x and y be n-element column vectors, u and v
be an m x n matrix, and B be an n x k matrix. For each of the expressions in the
accompanying table identify the result as being either a scalar, vector, or matrix, or
illegal. If the result is a vector or matrix, specify the number of rows and columns
in the result. If the expression is legal for only certain combinations of m, n, and k,
identify those conditions.
