Abstract

The isomath package enables formatting Greek and Latin -letters as symbols for vectors, matrices, and tensors -in the typefaces recommended for scientific papers -by the International Standard ISO 80000-2.

The isomath package provides tools for a mathematical style +that conforms to the International Standard ISO 80000-2 and is +common in science and technology: capital Greek letters in italic +shape, bold italic and sans-serif bold italic math alphabets with +Latin and Greek characters, and macros for markup of vector, +matrix and tensor symbols.

Abstract

The isomath package sets up an “ISO math style” allowing the -use of Greek and Latin letters as symbols for scalars, -vectors, matrices, and tensors in the typefaces recommended -for scientific papers by the International Standard -ISO 80000-2.

The isomath package provides tools for a mathematical style +that conforms to the International Standard ISO 80000-2 and is +common in science and technology. It changes the default shape of +capital Greek letters to italic, sets up bold italic and +sans-serif bold italic math alphabets with Latin and Greek +characters, and defines macros for markup of vector, matrix and +tensor symbols.

In their style guides, e. g. [typefaces], [checklist], [SI], +[fonts_for_symbols], [Red-Book], [Green-Book], many international +scientific organisations recommend layout rules for mathematics in line with +the International Standard [ISO-80000-2].

International standard layout rules

The overall rule is that symbols representing physical quantities (or variables) are italic, but symbols representing units, or labels, are roman.
Symbols for vectors are boldface italic, symbols for tensors are -sans-serif bold italic, and symbols for matrices are boldface -italic.
The above rules apply equally to letter symbols from both the Greek -and the Latin alphabet.
Symbols for vectors and matrices are bold italic, symbols for tensors +are sans-serif bold italic.
The above rules apply equally to letter symbols from the Greek and the +Latin alphabet.

TeX's default mathematical style deviates from this rules in several points:

capital Greek letters default to upright shape,
small Greek letters are excluded from font changes with the math -alphabets.

Capital Greek letters default to upright shape,
small Greek letters are excluded from font changes with the math +alphabet commands, and
the \vec command produces an arrow accent.

The isomath package implements an ISO math style and provides -new math alphabets with bold italic and sans-serif bold italic -typeshape that can be used for vector and tensor symbols.

The isomath package implements an “ISO” math style, provides new math +alphabets with bold italic and sans-serif bold italic type and macros +for semantic markup of vector, matrix and tensor symbols. It can be +combined with most packages for mathematical typesetting (see +isomath-test.tex and the sections on alternatives and conflicts).

1.1 ISO math style

The required package fixmath changes the default math layout to the -“ISO” math style:

1.1 “ISO” math style

Isomath builds on the package fixmath by Walter Schmidt to change the +default mathematics layout to the “ISO” math style:

Uppercase Greek letters are typeset italic by default.
Capital Greek letters are typeset in italic shape by default.
Both, Greek and Latin letters change shape if a different math alphabet is used.

However, fixmath works only for the Computer Modern font family. -With isomath,

the used math fonts are configurable (using the rmdefault and -sfdefault options), and
upright Greek letters can be made available through the common -\math* alphabets via the OMLmath* options if the -corresponding fonts support the OML font encoding.

Caution!

Using Greek letters in standard math alphabets, e. g., -\mathrm{\pi}, can lead to garbage, as the standard math -alphabets are usually taken from text fonts that have ligatures and -non-alpha symbols in place of the small Greek letters. -Do not use small Greek letters in the standard math alphabet commands -mathit, mathrm, mathbf, mathsf, and mathtt -unless you use the OMLmath* options.

Some packages provide alternative macros or options for upright -Greek letters (cf. Table 6).

Be careful with Greek letters in the argument of \mathit, \mathrm, +\mathbf, \mathsf, and \mathtt. By default, these math +alphabets use text fonts. Fonts in OT1 text font encoding have capital +(but not small) Greek letters at the expected places, T1 encoded text fonts +have no Greek letters at all.

See the examples section on how to get upright small Greek letters in +mathematical context.

Using the new math alphabets for numbers can result in upright -old-style numbers instead of italic ones, because some italic math -fonts (e. g., cmr, cmbr) have old-style numbers in place of italic -digits.
