.SH DESCRIPTION
Left and right parenthesis are used to specify evaluation order within 
expressions, to form right-hand-side functions argument list and to 
select elements within matrices and lists.
.LP
Within multiple rhs  arguments must be separated by comma.

For elements selection  \fVi\fR, \fVj\fR, may be real scalar or vectors 
or then \fV : \fR symbol which stands for "all elements".
