Detailed Description

Extracts the diagonal of a matrix.

Syntax

subroutine extract_diagonal(real(real64) a(:,:), real(real64) diag(:), optional class(errors) err)
subroutine extract_diagonal(complex(real64) a(:,:), complex(real64) diag(:), optional class(errors) err)
subroutine extract_diagonal(class(csr_matrix) a, real(real64) diag(:), optional class(errors) err)

Parameters

[in]	a	The M-by-N matrix.
[out]	diag	The MIN(M, N) element array for the diagonal elements.
[in,out]	err	An optional errors-based object that if provided can be used to retrieve information relating to any errors encountered during execution. If not provided, a default implementation of the errors class is used internally to provide error handling. Possible errors and warning messages that may be encountered are as follows. LA_ARRAY_SIZE_ERROR: Occurs if @diag is not sized correctly.
