Matrices as well as vectors are the building blocks of MATLAB and are used in various science and engineering applications. Sometimes we require to change the dimension of a matrix or a vector, such as can transform a matrix into a row or column vector and vice versa. Turning a matrix into a row vector is useful because it is easy to manipulate a row vector instead of a matrix.

This blog is going to explore how to convert a matrix into a row vector in MATLAB.

How to Transform a Matrix into a Row Vector in MATLAB?

We can transform the matrix into the row vector in MATLAB utilizing the reshape() function. The reshape() is a built-in function in MATLAB that enables us to alter an array’s dimension. This function is used for converting a matrix into a row vector. This function accepts two arguments as input and returns a row vector that is the transformation of the provided matrix and contains all elements of the provided matrix.

Syntax

To convert a matrix into a row vector, the reshape() function uses the following syntax:

Here:

The function vect = reshape(A,sz) yields to turn a matrix into a row vector having specified size sz. The matrix A’s cardinality must be the same as the size of the row vector. For example, if the given matrix A’s dimension is 5-by-2 then the sz should be 1-by-10.

Examples

In this section, we will understand the working of the reshape() function to convert a matrix into a row vector by performing some examples in MATLAB.

Example 1: How to Convert a Square Matrix into the Row Vector Utilizing the reshape() Function?

The given example creates a square matrix having size n = 3. After that, it uses the reshape() function to convert this matrix into a row vector having size 1-by-9.

Example 2: How to Convert a Rectangular Matrix into the Row Vector Utilizing the reshape() Function?

In the given MATLAB code, we create a rectangular matrix having a size of 2-by-3. After that, we use the reshape() function to convert this matrix into a row vector having size 1-by-6.

Conclusion

MATLAB is a beneficial programming language that allows us to perform various matrix operations. It facilitates us to convert a matrix into a row vector using the built-in reshape() function. This function accepts a matrix and the size of the obtained row vector as arguments and returns a row vector having the cardinality the same as the given matrix. This guide has discovered how to transform a matrix into a row vector in MATLAB using the reshape() function.
