Detailed Description

Extracts the diagonal from a matrix.

Parameters

[in]	nrow	The number of rows.
[in]	ncol	The number of columns.
[in]	job	Set to 0 to not alter a, ja, and ia; else, set to a non-zero value to perform this as an in-place operation.
[out]	len	The number of non-zero elements found in diag.
[out]	idiag	An array of length len containing the original positions in the original arrays a and ja of the diagonal elements collected in diagl.
[in]	ioff	The offset of the wanted diagonal.
