Declaring math alphabets

\DeclareMathAlphabet {<math-alph>} {<encoding>} {<family>} {<series>} {<shape>}

Defines <math-alph> to be a new math alphabet.

The arguments <encoding> <family> <series> <shape> are the default values for this math alphabet in all math versions; these can be reset later for a particular math version by a \SetMathAlphabet command. If <shape> is empty then the <math-alph> is declared to be invalid in all versions, unless it is set by a later \SetMathAlphabet command.

Checks that <math-alph> can be used and that <encoding> is a valid encoding scheme.

In these examples, \foo is defined everywhere but \baz, by default, is defined nowhere.


\SetMathAlphabet {<math-alph>} {<version-name>}
{<encoding>} {<family>} {<series>} {<shape>}

Changes, or sets, the font for the math alphabet <math-alph> in math version <version-name> to <encoding><family><series><shape>.

Checks that <math-alph> is a math alphabet, <version-name> is a math version and <encoding> is a known encoding scheme.

This example defines \baz for the `normal' math version only:


Note that this declaration is not used for all math alphabets: Section 3.5 describes \DeclareSymbolFontAlphabet, which is used to set up math alphabets contained in fonts which have been declared as symbol fonts.
