Matrix transpose in MATLAB - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the matrix transpose operation do?

It flips a matrix over its diagonal, turning rows into columns and columns into rows.

beginner

How do you transpose a matrix A in MATLAB?

Use the apostrophe operator: A'.

intermediate

What is the difference between A' and A.' in MATLAB?

A' computes the complex conjugate transpose, while A.' computes the simple transpose without conjugation.

beginner

If A is a 2x3 matrix, what will be the size of A'?

The size will be 3x2 because transpose swaps rows and columns.

beginner

Why is matrix transpose useful in real life?

It helps to rearrange data, solve equations, and work with vectors in different orientations, like switching between rows and columns in a spreadsheet.

What MATLAB operator is used to transpose a matrix?

A /

B .

C *

D '

The apostrophe (') operator transposes a matrix in MATLAB.

If A is a 4x2 matrix, what is the size of A'?

A 4x2

B 2x4

C 2x2

D 4x4

Transpose swaps rows and columns, so 4x2 becomes 2x4.

What does A.' do in MATLAB?

A Simple transpose without conjugate

B Complex conjugate transpose

C Matrix inverse

D Element-wise transpose

A.' transposes the matrix without conjugating complex numbers.

Which of these is true about matrix transpose?

A Only works on square matrices

B Matrix size stays the same

C Rows become columns

D Multiplies all elements by -1

Transpose flips rows and columns, changing their positions.

Why might you use transpose in data processing?

A To switch data orientation from rows to columns

B To delete data

C To add new rows

D To sort data alphabetically

Transpose helps rearrange data orientation for easier processing.

Explain how to transpose a matrix in MATLAB and the difference between A' and A.'.

Think about how MATLAB handles complex numbers with transpose.

Describe a real-life situation where transposing a matrix would be helpful.

Consider how you might want to view data differently.
