Equivalence (mathematics) | Matrices
In linear algebra, two n-by-n matrices A and B are called similar if there exists an invertible n-by-n matrix P such that Similar matrices represent the same linear map under two (possibly) different bases, with P being the change of basis matrix. A transformation A ↦ P−1AP is called a similarity transformation or conjugation of the matrix A. In the general linear group, similarity is therefore the same as conjugacy, and similar matrices are also called conjugate; however, in a given subgroup H of the general linear group, the notion of conjugacy may be more restrictive than similarity, since it requires that P be chosen to lie in H. (Wikipedia).
Similar matrices have similar properties
We define a notion of "Similar Matrices" where two matrices that are similar share many similar properties like eigenvalues, but don't share others like eigenvectors. This notion comes about via the idea of a change of basis Learning Objectives: 1) Apply properties of determinants to for

The Similarity Relationship Represents a Change of Basis
Description: The formula P^-1AP=D is called similarity. We interpret this geometrically as being a change of basis. Learning Objective: Given two similar matrices, find a matrix that represents the transformation in the basis described by the similarity relation. This video is part of

How do we add matrices. A matrix is an abstract object that exists in its own right, and in this sense, it is similar to a natural number, or a complex number, or even a polynomial. Each element in a matrix has an address by way of the row in which it is and the column in which it is. Y

Similarity Transformation and Diagonalization
In this video we investigate similarity transformations in the context of linear algebra. We show how the similarity transformation can be used to transform a square matrix into another square matrix that shares properties with the original matrix. In particular, the determinant, eigenva
