\documentclass{article} . . \usepackage[spacesep,definevectors]{easyvector} . .The package option spacesep means that the separator for the indices is the command \smallspace instead of ``
,
'' (comma).
The package option definevectors means that the command
\aa,..., \zz and \AA,...,
\ZZ are predefined as vectors. It also defines the commands
\Balpha, \Bbeta and so on, as bold greek vectors.
The latex commands \aa, \AA, \gg,
\ll, \ss, \SS, \tt are saved in
the commands \oldxx where xx
is the name of the old
command.
\newvector[\cmda,\cmdb]{cmd}or
\newvector(a)[cmd]In the first case, it creates the new command (macro) \cmd which executes \cmda when in scalar mode and \cmdb when in vector mode. In the second case it creates a new command \cmd which substitutes the letter \mathit
{a}
when in scalar, mode and \mathbf{a}
when in vector
mode. Scalar mode is activated when \cmd is immediately
followed by [
. In scalar mode everything between
[
and ]
(with balancing) is assumed to be as an index.
For example the commands
|
The structure of the [...]
command is the following
[i,j,...,k;x,y,...,z]where
i,j,...,k
are subscripts and x,y,...,z
are
superscripts. The comma ``,
'' is used as a separator
between different indices, and the semi-colon ``;
'' separates
subscripts and superscripts. There are no limits on the number of
indices, and the code is reentrant, as the following example
illustrates
|
!
before [

Important: For old users (version ) the command
\customindex is suppressed and the \newcustomvector
is used instead.
