Description
The
?sctr
 routines scatter the elements of the compressed sparse vector (
nz
,
x
,
indx
) to a full-storage vector
y
. The routines modify only the elements of
y
 whose indices are listed in the array
indx
:
y
[
indx
[
i
]] =
x
[
i
]
, for
i
=0,1,... ,
nz
-1
.
Input Parameters
nz
The number of elements of
x
 to be scattered.
indx
Specifies indices of elements to be scattered.
Array, size at least
nz
.
x
Array, size at least
nz
.
Contains the vector to be converted to full-storage form.
Output Parameters
y
Array, size at least max(
indx[i]
).
Contains the vector
y
 with updated elements.
