WebHence a central matrix a 0 is of the form , i.e. it is a scalar matrix. Of course we must have a 6= 0 for the 0 a matrix to be invertible. In conclusion, we have proved ... • aG = {a} if and only if a ∈ Z(G). Indeed, aG = {a} means that xax−1 = a for all x, i.e. xa = ax for all x ∈ G. … WebThe term scalar is also sometimes used informally to mean a vector, matrix, tensor, or other, usually, "compound" value that is actually reduced to a single component. Thus, for example, the product of a 1 × n matrix and an n × 1 matrix, which is formally a 1 × 1 matrix, is often said to be a scalar .
