# Vector vs. Matrix: What's the Difference?

Edited by Sara Rehman || By Huma Saeed || Published on December 3, 2023

**A vector is a one-dimensional array of numbers, while a matrix is a two-dimensional array of numbers.**

## Key Differences

A vector is a sequence of numbers arranged in order, representing a point in space with magnitude and direction, whereas a matrix is a rectangular array of numbers organized into rows and columns. Each element in a vector is a component of that vector, while in a matrix, each element belongs to both a row and a column.

In mathematical operations, vectors often represent quantities with both magnitude and direction, such as force or velocity. Matrices, on the other hand, are used to represent and solve systems of linear equations, transformations, and more complex operations in higher dimensions.

The visualization of a vector is typically a directed line segment in a coordinate system, pointing from the origin to a point in space. A matrix, however, is visualized as a grid of numbers, where the position of each number is significant to its function and interpretation.

Vectors can be added or subtracted directly if they are of the same dimension, using their corresponding components. Matrices can also be added or subtracted, but this requires that they have the same number of rows and columns.

Vectors can be scaled by multiplying each component by a scalar value, affecting its magnitude but not its direction. Matrices can undergo similar scalar multiplication, but they can also be multiplied by other matrices or vectors, a process that involves combining rows and columns in a specific way.
