@deftypefn {Built-in Function} {} subsref (@var{val}, @var{idx})\n\
Perform the subscripted element selection operation according to\n\
the subscript specified by @var{idx}.\n\
\n\
The subscript @var{idx} is expected to be a structure array with\n\
fields @samp{type} and @samp{subs}. Valid values for @samp{type}\n\
are @samp{\"()\"}, @samp{\"@{@}\"}, and @samp{\".\"}.\n\
The @samp{subs} field may be either @samp{\":\"} or a cell array\n\
of index values.\n\
\n\
The following example shows how to extract the two first columns of\n\
a matrix\n\
\n\
@example\n\
@group\n\
val = magic(3)\n\
@result{} val = [ 8 1 6\n\
3 5 7\n\
4 9 2 ]\n\
idx.type = \"()\";\n\
idx.subs = @{\":\", 1:2@};\n\
subsref(val, idx)\n\
@result{} [ 8 1 \n\
3 5 \n\
4 9 ]\n\
@end group\n\
@end example\n\

Note that this is the same as writing @code{val(:,1:2)}.\n\

Perform the subscripted assignment operation according to\n\

The following example shows how to set the two first columns of a\n\
