<title>Description</title>
<para>
Left and right brackets are used to note vector and matrix concatenation.
These symbols are also used to denote a multiple left-hand-side for a function
call</para>
<para>
Inside concatenation brackets, blank or comma characters mean
"column concatenation", semicolon and carriage-return mean
"row concatenation".</para>
<para>
Note : to avoid confusions it is safer to use commas instead of blank to
separate columns.</para>
<para>
Within multiple lhs brackets variable names must be separated by comma.</para>
