.SH NAME
parents ( ) - left and right parenthesis
.SH CALLING SEQUENCE
.nf
(expression)
[...]=func(e1,e2,...)
[x1,x2,...]=(e1,e2,...)
x(i,j)
v(i)
[...]=l(i)
.fi
.SH PARAMETERS
.TP 15
x
: matrix of any possible type
.TP 15
v
: row or column vector of any possible type
.TP 15
l
: list variable
.TP 15
func
: any function name
.TP 15
e1,e2,...
: any possible type expression
.SH DESCRIPTION
Left and right parenthesis are used to
.IP *
Specify evaluation order within expressions,
.IP *
Form right-hand-side functions argument list. Within multiple rhs
arguments must be separated by comma.
.IP *
Select elements within vectors, matrices and lists.
see help on extraction and insertion for more precisions
.IP *
[x1,x2,...]=(e1,e2,...) is equivalent to first performing %t_1 = e1,
%t_2 = e2, ..., and then x1 = %t_1, x2 = %t_2, ..., where the
variables %t_i, i = 1, 2, ... are invisible to the user.
.SH EXAMPLE
.nf
3^(-1)
x=poly(0,"x");
//
(x+10)/2
i3=eye(3,3)
//
a=[1 2 3;4 5 6;7 8 9],a(1,3),a([1 3],:),a(:,3)
a(:,3)=[]
a(1,$)=33
a(2,[$ $-1])
a(:,$+1)=[10;11;12]
//
w=ssrand(2,2,2);ssprint(w)
ssprint(w(:,1))
ss2tf(w(:,1))
//
l=list(1,2,3,4)
[a,b,c,d]=l(:)
l($+1)='new'
//
v=%t([1 1 1 1 1])
//
[x,y,z]=(1,2,3)
