Technical writing is not only about boring, text-heavy instruction manuals. It's about conveying technical information in a way that is user friendly, clear, and concise.
In this doc post, we'll guide you through the steps of changing the diagonal of a Matrix in MATLAB. You will also find an FAQ section with a minimum of 5 questions to answer any doubts you might have during the process.
Step-By-Step Guide
1. Defining your Matrix
The first step is to define your matrix A. A matrix is a rectangular array of elements arranged in rows and columns, such as
A=[1 2 3; 4 5 6; 7 8 9]
2. Outputting the Diagonal Elements
Then, you can output the diagonal elements of A by using the command diag(A)
3. Store the Diagonal Elements in a Vector
You can then store the diagonal elements into a Vector by using the command v=diag(A).
4. Change the Diagonal Elements
You can then change the elements by using the command v(2)=27
5. Storing the Changed Vector into Matrix
You can store the changed Vector back in Matrix A by using the command A=diag(v)
