In graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph. So, what is adjacency matrix interior design? We will discuss it in this article.

The elements of the matrix in computer science indicate whether pairs of vertices are adjacent or not in the graph. It is the same in interior design.

In interior design, an interior designer or a design studio can use an adjacency matrix to show a correlation between rooms. Let’s talk more about what you need to know and how to understand it.

## What is an adjacency matrix diagram?

Let’s talk about some aspects of adjacency matrix interior design. The adjacency matrix, which we also refer to as the connection matrix, is a simple labeled graph, a matrix with rows and columns labeled by graph vertices.

There are values 1 or 0 in position according to whether they are adjacent or not. For a simple graph with no self-loops, the adjacency matrix must have 0s in the diagonal.

## What is a bubble diagram?

Any architect and interior designer can create a bubble diagram. What is it? It is a freehand diagram made at the preliminary programming phase of the design process.

What is the purpose of the bubble diagram? Architects and interior designers create this diagram to graphically illustrate the program or a list that itemizes the spaces that must take place in the building during the design phase.

## Proximity matrix in architecture

Here is another matrix that we see in architecture. What is a proximity matrix? It is the simplest form of a diagram illustrating the spacial relationships of the proposed building. In this matrix, a series of icons have preset meanings. This allows for the easy comprehension of the required spacial relationships.

## How to fill an adjacency matrix?

Now we are talking about the important aspect. How to fill a matrix? Well, to fill the adjacency matrix, you have to look at the name of the vertex in rows and columns.

If they are connected by an edge or more, you count the number of edges and put the number as a matrix element.

This matrix, which represents a graph is called adjacency matrix.

## What is an adjacency diagram in interior design?

We said adjacency matrix is a term we use in different fields. What is its meaning in interior design? It is a diagram or table that lists each room or space.

What is the purpose? Well, these diagrams help an interior designer see the connection between the spaces. That is how he can develop the needs of the client.

## Reading an adjacency matrix

A big part of understanding an adjacency matrix interior design is to know how to read an adjacency matrix. A simple Google search will return tables so complex that you might forget all about the idea of creating one yourself.

But do not worry, reading any size matrix is easy. Here is how.

- All programmed spaces are listed on one side of the table
- See what the adjacencies of two spaces are, and locate the two area names
- Then, follow their rows of boxes to see where they intersect
- The box at the intersection contains a symbol associated with different adjacency type
- Among the common adjacency types, you will see primary adjacencies, or spaces directly next to each other, secondary, spaces close to each other, and undesired adjacencies, spaces that should not be close to each other

The symbols might be different, according to a specific interior designer, but usually, they follow the same principles. In that regard, a solid circle is a primary adjacency. Circle outline is secondary adjacency. And horizontal line signifies undesired adjacency.

## How to create an adjacency matrix?

You might think creating an adjacency matrix interior design is a challenging task. But it is simple and easy once you find the right program to use. There are a lot of apps and programs you can use for the programming phase and the design phase. Playing with different online charting systems will help you find the one that suits you best.

Among the many, you can try lucidchart, draw.io, or AutoCAD. The last one, AutoCAD is best for drawing your matrix, plotting it, and then rendering it.

As we said before, matrices are widely used in business or marketing. They help visualize the relationship between groups of information, usually two vertical or horizontal binary axes. The shape used in the adjacency matrix diagram is editable, including a wide range colors and sizes.

We have to stress another thing. The adjacency matrix is more than just a presentation graphic. It dynamically shows what is in the drawing. And it can update automatically when spaces or space links change in the matrix.

With that in mind, use any tool to create it. Once you understand how the numbers and symbols work, an adjacency matrix is quite useful in interior design. It will help you better understand the space of your apartment, house, or any home.
