Question

Transpose of a column matrix is________________

(a) Zero matrix

(b) Identity matrix

(c) Row matrix

(d) Diagonal matrix

I had been asked this question in an interview.

My doubt stems from Composite 2D Transformations in portion 2D Transformation and Viewing of Computer Graphics

Answer 1

Right choice is (c) Row matrix

To explain I would say: Transpose of a matrix is a matrix which is made by interchanging the rows and columns of the original matrix. Hence the transpose of column matrix is row matrix and vice versa.
