Detailed Description

Converts the LINPACK, BLAS, LAPACK banded matrix format into a CSR format.

Parameters

[in]	n	The row dimension of the matrix.
[in]	abd	The banded matrix.
[in]	nabd	The leading dimension of `abd`.
[in]	lowd	The row index where the lowest diagonal (leftmost) of A is located. LINPACK uses LOWD = 2 * ML + MU + 1.
[in]	ml	The bandwidth of the strict lower part of A.
[in]	mu	The bandwidth of the strict upper part of A.
[out]	a	The non-zero elements of matrix A.
[out]	ja	The column indices of matrix A.
[out]	ia	The index in A where the requested row starts.
[in]	len	The length of `a` and `ja`.
[out]	ierr	Error message output. 0: Normal return. -1: Invalid `lowd` value. Positive Valued: Not enough storage in `a` and `ja`.
