In which of the scripts that follow matrix R is an orthonormal (or orthogonal) matrix. Remember, an orthogonal matrix is one whose transpose is its inverse. This means that if we multiply a matrix by its inverse the result is the identity matrix. Select one: a. A=rand(3,3); R = A + inv(A) b. A=rand(3,3); S=A-A' R = (eye(3)-S)*(eye(3)+S); c. A=rand(3,3); R = A + inv(A') d. A=rand(3,3); R = A - inv(A) e. A=rand(3,3); S=A-A' R = inv(eye(3)-S)*(eye(3)+S);

Question

In which of the scripts that follow matrix R is an orthonormal (or orthogonal) matrix. Remember, an orthogonal matrix is one whose transpose is its inverse. This means that if we multiply a matrix by its inverse the result is the identity matrix.

Select one:
a.

A=rand(3,3);
R = A + inv(A)

b.

A=rand(3,3);
S=A-A'
R = (eye(3)-S)*(eye(3)+S);

c.

A=rand(3,3);
R = A + inv(A')

d.

A=rand(3,3);
R = A - inv(A)

e.

A=rand(3,3);
S=A-A'
R = inv(eye(3)-S)*(eye(3)+S);
