▷ How to find the transpose of a matrix (examples)

On this article, we clarify just how to discover the transpose of a matrix. You will certainly additionally see addressed issues to ensure that you believe concerning just how to shift a matrix. As well as lastly, we will reveal you all the buildings of the transpose of a matrix.

Exactly how to discover the transpose matrix?

To find the transpose of a matrix, exchange the rows of the matrix for its columns, that is, the rows of the shifted matrix are the columns of the initial matrix and also the columns of the shifted matrix are the rows of the initial matrix.

Hence, the transpose of a matrix is the matrix gotten by switching over the rows of the matrix by its columns. In addition, the transpose of a matrix is suggested by composing a “T” on top right of the matrix (A^T).

Instance of the transpose of a matrix

Once we have actually seen the interpretation of the transpose of a matrix, allow’s see an instance of just how to determine the transpose of a matrix. We are mosting likely to shift the adhering to matrix:

$displaystyle A= begin{pmatrix} 2 & 3 & 1 \[1.1ex] 4 & 5 & 0 end{pmatrix}$

To shift matrix A we simply need to interchange its rows for its columns. So, the very first row of the matrix comes to be the very first column of the matrix, and also the 2nd row of the matrix comes to be the 2nd column of the matrix:

$displaystyle A^T= begin{pmatrix} 2 & 4 \[1.1ex] 3 & 5 \[1.1ex] 1 & 0 end{pmatrix}$

Realistically, the measurement of a matrix adjustments when it is shifted. In this situation, matrix A was a 2 × 3 measurement matrix, and also its transpose is a 3 × 2 measurement matrix.

As you can see, there is no formula to discover the transpose of a matrix, yet shifting a matrix is not really made complex: you simply need to turn the matrix over its angled.

Method issues on transpose of a matrix

Below are numerous addressed issues to ensure that you can exercise just how to shift a matrix.

Trouble 1

Transpose the adhering to 2 × 2 matrix:

$displaystyle A= begin{pmatrix} 1 & 5\[1.1ex] 7 & 2 end{pmatrix}$

$displaystyle A^T= begin{pmatrix} 1 & 7\[1.1ex] 5 & 2 end{pmatrix}$

Problem 2

Find the transpose of the adhering to 3 × 3 matrix:

$displaystyle B= begin{pmatrix} -1 & 4 & 3 \[1.1ex] 5 & 3 & 2 \[1.1ex] 6 & 0 & 9 end{pmatrix}$

$displaystyle B^T= begin{pmatrix} -1 & 5 & 6 \[1.1ex] 4 & 3 & 0 \[1.1ex] 3 & 2 & 9 end{pmatrix}$

Problem 3

Transpose the adhering to matrix created by one solitary row:

$displaystyle C= begin{pmatrix} 2 & 6 & -1 end{pmatrix}$

$displaystyle C^T= begin{pmatrix} 2 \[1.1ex] 6 \[1.1ex] -1 end{pmatrix}$

The transpose of a row matrix is constantly a column matrix. As well as the other way around, shifting a column matrix constantly causes a row matrix.

Problem 4

Calculate the transpose of the adhering to rectangle-shaped matrix:

$displaystyle D= begin{pmatrix} 9 & 0 \[1.1ex] 2 & -1 \[1.1ex] 5 & 3 end{pmatrix}$

$displaystyle D^T= begin{pmatrix} 9 & 2 & 5 \[1.1ex] 0 & -1 & 3 end{pmatrix}$

Problem 5

Transpose the adhering to square 4 × 4 matrix:

$displaystyle E= begin{pmatrix} 0&5&6&-2\[1.1ex]4&-1&9&0\[1.1ex]8&2&-2&11\[1.1ex]7&-3&4&3end{pmatrix}$

$displaystyle E^T= begin{pmatrix}0&4&8&7\[1.1ex]5&-1&2&-3\[1.1ex]6&9&-2&4\[1.1ex]-2&0&11&3end{pmatrix}$

Properties of the transpose of a matrix

The transpose of a matrix has the adhering to qualities:

Involutory residential or commercial property: The transpose of a shifted matrix amounts to the initial matrix.

$left(A^Tright)^T = A$

Distributive residential or commercial property: including 2 matrices and afterwards shifting the outcome coincides as shifting each matrix very first and afterwards including them:

$left(A+Bright)^T=A^T+B^T$

See: matrix addition

Linear residential or commercial property (item of shifted matrices): increasing 2 matrices and afterwards shifting the outcome amounts shifting each matrix very first and afterwards increasing them yet altering their order of reproduction:

$left(Acdot Bright)^T=B^Tcdot A^T$

See: matrix multiplication

Linear Building (scalar): shifting the outcome of the item of a matrix by a scalar coincides as increasing the currently shifted matrix by the scalar.

$left(ccdot Aright)^T=ccdot A^T$

Component of a shifted matrix: the component of a matrix equals to the component of its transpose.

$det(A)=det(A^T)$

Inverse of a shifted matrix: computing the inverse of a shifted matrix coincides as very first computing its inverted and afterwards shifting the outcome.

$left(A^Tright)^{-1}=left(A^{-1}right)^T$

Hence, if a matrix is invertible, the transpose of that matrix is additionally invertible.

Symmetrical matrix: when the transpose of a matrix causes the exact same matrix, this matrix is called symmetrical matrix.

$A^T=A$

Antisymmetric matrix: when the transpose of a matrix causes the exact same matrix yet with all components altered indication, it is an antisymmetric matrix, additionally called skew-symmetric matrix.

$A^T=-A$
