@item (vec_concat:@var{m} @var{x1} @var{x2})
Describes a vector concat operation. The result is a concatenation of the

@findex vec_duplicate
@item (vec_duplicate:@var{m} @var{vec})
This operation converts a small vector into a larger one by duplicating the
input values. The output vector mode must have the same submodes as the
input vector mode, and the number of output parts must be an integer multiple
of the number of input parts.
@item (vec_duplicate:@var{m} @var{x})
This operation converts a scalar into a vector or a small vector into a
larger one by duplicating the input values. The output vector mode must have
the same submodes as the input vector mode or the scalar modes, and the
number of output parts must be an integer multiple of the number of input
parts.
