Detailed Description

Computes the determinant of a square matrix.

Syntax

real(real64) function det(real(real64) a(:,:), optional integer(int32) iwork(:), optional class(errors) err)
complex(real64) function det(complex(real64) a(:,:), optional integer(int32) iwork(:), optional class(errors) err)

Parameters

[in,out]	a	On input, the N-by-N matrix on which to operate. On output the contents are overwritten by the LU factorization of the original matrix.
[out]	iwork	An optional input, that if provided, prevents any local memory allocation. If not provided, the memory required is allocated within. If provided, the length of the array must be at least N-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 any of the input arrays are not sized appropriately. LA_OUT_OF_MEMORY_ERROR: Occurs if local memory must be allocated, and there is insufficient memory available.

Returns

The determinant of a.
