... A rectangular array of mn real numbers written in m rows and n columns is called a matrix of the type m n (read: type m by n or shortly an m by n matrix). The numbers which are contained in the matrix are called its entries or its elements. Matrices are usually denoted by capital letters and thei ...

... Matrix multiplication of a linear combination of vectors is a linear operation since A(x + y) = Ax + Ay where L = A and and are scalars. In general, an operation that transforms a vector in Rn (vector with n real components) to a vector in Rm is linear if and only if it coincides with multip ...
