subroutine	csrcsc2 (n, n2, job, ipos, a, ja, ia, a0, ja0, ia0)

Detailed Description

Converts a CSR matrix into a CSC matrix (transposition).

Parameters

[in]	n	The number of rows in the CSR matrix.
[in]	n2	The number of columns in the CSC matrix.
[in]	job	Fill the values (job == 1) or only the pattern (job /= 1).
[in]	ipos	Starting position of A0 in JA0.
[in]	a	The non-zero elements of matrix A.
[in]	ja	The column indices of matrix A.
[in]	ia	The index in A where the requested row starts.
[out]	a0	The non-zero elements of the transposed array.
[out]	ja0	The size NNZ array containing the column indices.
[out]	ia0	The N+1 size array containing the column starts.
