SymbolsMeaning

A, a, f, m, n, k Unless specified otherwise, normal font designates scalars
, Italic font designates vectors. Different vectors can be distinguished by the left-superscript notation
A, a, Abc, Pan, SaBold font designates operators or matrices (here all operators are matrices)
, , , Operators can be distinguished by the left-superscript notation. For sampling operator Sa, this notation specifies the sampling fraction of the Sa operator
A1, a2, , Normal font with right subscript designates scalar values of the vector
A11, A21, Aij, AiiNormal font with two right subscripts designates scalar values of the 2D matrix
Description of the scalar elements in the vector
Description of the scalar elements in the matrix
x  [A B]Scalar x belongs to the inclusive scalar interval [A B]; that is, A ≤ x ≤ B
Vector x belongs to the “vector interval” ; that is, for every element Ai ≤ xi ≤ Bi
Set where A, B, C, , X are the unique elements of the set
{A(a) B(b) X(x)}Multiset (2-tuple) where A, B, , X are the unique elements and a, b, x are the scalars describing the copy numbers of the A, B, X elements
INUnity matrix of the Nth order; that is, N × N matrix , Aij = δ ij (Kronecker delta)
