An interface to the banded matrix to full matrix conversion routines.
Converts a banded matrix to a full matrix.
The banded matrix is stored in a compressed form supplied column by column. The following code segment transfers between a full matrix to the bonded matrix storage scheme. \code{fortran} do j = 1, n k = ku + 1 - j do i = max(1, j - ku), min(n, j + kl) a(k + i, j) = matrix(i, j) end do end do \endcode
| Type | Intent | Optional | Attributes | Name | ||
|---|---|---|---|---|---|---|
| integer(kind=int32), | intent(in) | :: | kl |
The number of subdiagonals in the banded matrix. |
||
| integer(kind=int32), | intent(in) | :: | ku |
The number of superdiagonals in the banded matrix. |
||
| real(kind=real64), | intent(in), | dimension(:,:) | :: | b |
The banded matrix to convert. |
|
| real(kind=real64), | intent(out), | dimension(:,:) | :: | f |
The full matrix to store the result in. |
|
| class(errors), | intent(inout), | optional, | target | :: | err |
An error object to report any errors that occur. |
