Inserting a Row Vector into a Matrix in Matlab: A Step-by-Step Guide

When working with matrices in Matlab, it's often necessary to insert a row vector into an existing matrix. This can be a bit tricky if you're new to the platform, but don't worry - we've got you covered.

To start, let's say you have a matrix that looks like this:

| 1 | 2 | 3 |

| 4 | 5 | 6 |

| 7 | 8 | 9 |

And you want to insert a row vector into the middle of the matrix. The first step is to define your row vector. In Matlab, you can do this by typing in a series of numbers separated by commas and enclosed in square brackets.

For example, let's say you want to create a row vector with the values 10, 11, and 12. You would type in:

'10, 11, 12'

This will create a new row vector with the specified values.

The next step is to insert this row vector into your original matrix. To do this, you'll need to use the 'vertcat' function, which stands for vertical concatenation. This function allows you to concatenate two matrices vertically, creating a new matrix that contains both of the original matrices.

Here's an example of how you might use the 'vertcat' function to insert your row vector into your original matrix:

| 1 | 2 | 3 |

| 4 | 5 | 6 |

'10; 11; 12'

| 7 | 8 | 9 |

By using the 'vertcat' function, you can easily insert a row vector into an existing matrix in Matlab. This is just one of many ways to manipulate matrices in Matlab - we'll be exploring more advanced techniques in future videos.

In today's video on MATLAB basics, we're going to show how to store the results of a calculation inside of a vector, which is a special case of a matrix.
