# Functions, Benefits and Disadvantages of Matrix Information Construction

A matrix represents a group of numbers organized in an order of rows and columns. It’s essential to surround the weather of a matrix in parentheses or brackets.

For instance, A matrix with 9 components is proven beneath. Matrix

This Matrix [M] has 3 rows and three columns. Every component of matrix [M] may be referred to by its row and column quantity. For instance, a23 = 6.

### Forms of Matrix:

There are numerous varieties of matrices. A few of them are:

• Row matrix
• Column matrix
• Null matrix
• Sq. matrix
• Diagonal matrix
• Sparse matrix
• Spiral matrix
• Id matrix
• Triangular matrix
• Symmetric matrix

### Options of  Matrix Information Construction:

• Dimension: A matrix has a particular dimension, outlined by its variety of rows and columns.
• Component: A matrix’s row and column indices serve to establish every entry, which is known as a component.
