If a column vector A=[1 2 3 4], then fliplr(A) returnsa.a column vector [1 2 3 4]b.a row vector [1 2 4 3]c.a row vector [4 3 2 1]d.a column vector [4 3 2 1]

Break Down the Problem

1. Understand that A is a column vector.
2. Analyze the operation fliplr(A), which flips the vector from left to right.

Relevant Concepts

• fliplr is a function commonly used in programming languages and mathematical software that flips the order of elements in a row vector from left to right.

Analysis and Detail

1. The column vector $A$ is represented as: $A = \begin{pmatrix} 1 \\ 2 \\ 3 \\ 4 \end{pmatrix}$
2. When fliplr is applied to a column vector, it first converts it to a row vector. Then, it flips the elements:
   • The equivalent row vector is: $A' = \begin{pmatrix} 1 & 2 & 3 & 4 \end{pmatrix}$
3. After applying fliplr, the resulting row vector becomes: $\begin{pmatrix} 4 & 3 & 2 & 1 \end{pmatrix}$

Verify and Summarize

• The transformation takes the original order of the vector and reverses it, confirming that fliplr indeed produces a row vector with reversed elements.

Final Answer

c. A row vector $[4\ 3\ 2\ 1]$
