Declaring math alphabets

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

If this is the first declaration for <math-alph> then a new math alphabet with this as its command name is created.

The arguments <encoding> <family> <series> <shape> are used to set, or reset, the default values for this math alphabet in all math versions; if required, these must be further reset later for a particular math version by a \SetMathAlphabet command.

If <shape> is empty then this <math-alph> is declared to be invalid in all versions, unless it is set by a later \SetMathAlphabet command for a particular math version.

Checks that the command <math-alph> is either already a math alphabet command or is undefined; and that <sym-font> is a symbol font.

In these examples, \foo is defined for all math versions but \baz, by default, is defined nowhere.


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

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

Checks that <math-alph> has been declared as a math alphabet, <version> is a known 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.
