Imagine variables as temporary storage bins where we can stash our precious matrices. By assigning a variable to a matrix, we create a direct link between them. This allows us to:

• Refer to the matrix by its variable name, making our code more concise and readable. For example, instead of writing disp(matrix_1) multiple times, we can simply write disp(A) if A is the variable assigned to matrix_1.
• Access elements of the matrix through the variable. This makes it super easy to perform operations on specific elements, such as A(2, 3) to access the element in the 2nd row and 3rd column of our matrix.
• Modify the matrix using the variable. If we change the value of A, the changes will be reflected in the corresponding matrix, matrix_1. This is like having a master key that unlocks all the treasures stored within the matrix.

So, how do we assign a variable to a matrix? It’s as simple as this magical incantation: variable_name = matrix_name. For instance, if our matrix is named my_data, we can assign it to a variable called data with this spell: data = my_data.

And voila! We now have a powerful tool at our disposal, enabling us to manage and manipulate matrices with grace and efficiency. It’s like having a trusty sidekick in the world of MATLAB, always there to help us store, access, and modify our data like the coding wizards we are.
