?sctr
Converts compressed sparse vectors into full storage form.
Syntax
call ssctr(nz, x, indx, y )
call dsctr(nz, x, indx, y )
call csctr(nz, x, indx, y )
call zsctr(nz, x, indx, y )
call sctr(x, indx, y)

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=1,2,... ,nz.
Input Parameters
- nz
-
INTEGER. The number of elements of x to be scattered.
- indx
-
INTEGER. Specifies indices of elements to be scattered.
Array, size at least nz.
- x
-
REAL for ssctr
DOUBLE PRECISION for dsctr
COMPLEX for csctr
DOUBLE COMPLEX for zsctr
Array, size at least nz.
Contains the vector to be converted to full-storage form.
Output Parameters
- y
-
REAL for ssctr
DOUBLE PRECISION for dsctr
COMPLEX for csctr
DOUBLE COMPLEX for zsctr
Array, size at least max(indx(i)).
Contains the vector y with updated elements.
BLAS 95 Interface Notes
Routines in Fortran 95 interface have fewer arguments in the calling sequence than their FORTRAN 77 counterparts. For general conventions applied to skip redundant or reconstructible arguments, see BLAS 95 Interface Conventions.
Specific details for the routine sctr interface are the following:
- x
-
Holds the vector with the number of elements nz.
- indx
-
Holds the vector with the number of elements nz.
- y
-
Holds the vector with the number of elements nz.
