A generic matrix \({\mathbf {A}}_{m\times n}\) is an array of things (numbers, functions, objects) arranged in m rows and n columns: it can also be defined as an \(m\times n\) matrix, or a matrix with dimensions \(m\times n\) . The notation \(\mathbf {A}\) without subscripts can also be used when it is not necessary to specify the matrix dimensions.

摘要

A generic matrix \({\mathbf {A}}_{m\times n}\) is an array of things (numbers, functions, objects) arranged in m rows and n columns: it can also be defined as an \(m\times n\) matrix, or a matrix with dimensions \(m\times n\) . The notation \(\mathbf {A}\) without subscripts can also be used when it is not necessary to specify the matrix dimensions.
