In mathematics, an array refers to a systematic arrangement of numbers, variables, or objects in rows and columns. Arrays can be used to organize and represent data in a structured way, making calculations and solving problems more convenient.
Arrays can be one-dimensional or multi-dimensional.
1. One-dimensional arrays:
A one-dimensional array is a list of elements arranged in a single row or a single column. For example, [1, 2, 3, 4, 5] is a one-dimensional array with five elements.
2. Multi-dimensional arrays:
A multi-dimensional array is a combination of multiple one-dimensional arrays, forming a grid-like structure. The elements in a multi-dimensional array are accessed using two or more indices. For example, a two-dimensional array can be represented as follows:
[
[1, 2, 3],
[4, 5, 6],
[7, 8, 9]
]
In this example, the array has three rows and three columns, forming a 3×3 grid. The elements can be accessed by specifying the row and column indices. For instance, the element in the second row and third column is 6.
Arrays are commonly used in various mathematical concepts, such as matrices, vectors, and arrays in programming languages. They provide a convenient way to store and manipulate data efficiently.
