Annex A (informative):
Preferred mathematical notations

The following table contains the preferred mathematical notations used in L1 documentation.

Item

Notation

multiply product

cross sign, e.g. ab

matrix product

dot sign, e.g. ab

scalar product (product of a matrix by a scalar)

dot sign, scalar should precede matrix e.g. 

matrix dimensioning

number of rows  number of column, e.g.:

RC

Kronecker product

ab

bracketing of sets (all elements of same type, not ordered elements)

curly brackets {}, e.g.

{a1, a2, …,ap}, or

bracketing of lists (all elements not necessary of same type, ordered elements)

round brackets (), e.g. (A, u, x)

bracketing of sequences (all elements of same type, ordered elements)

angle brackets, e.g. <a1, a2, …,ap> or

bracketing of function argument

round brackets, e.g. f(x)

bracketing of array index

square brackets, e.g. a[x]

bracketing of matrix or vector

square brackets [], e.g. , , or

Separation of indexes

use a comma : e.g. Ni,j

use of italic for symbols

a symbol should be either in italic or in normal font, but mixing up should be avoided.

bracketing of arithmetic expression to force precedence of operations

round brackets : e.g.

necessity of bracketing arithmetic expressions

When only + and  bracketing is not necessary. When the mod operator is used explicit bracketing of mod operands and possibly result should be done.

number type

in a context of non negative integer numbers, some notes should stress when a number is signed, or possibly fractional.

binary xor and and

respectively use + or . If no "mod 2" is explicitly in the expression some text should stress that the operation is modulo 2.

matrix or vector transpose

vT

11 matrices

implicitly cast to its unique element.

vector dot product

uTv for column vectors, and uvT for line vectors

complex conjugate

v*

matrix or vector Hermitian transpose

vH

real part and imaginary part of complex numbers.

Re(x) and Im(x)
