public class DASUM
extends java.lang.Object

DASUM is a simplified interface to the JLAPACK routine dasum.
This interface converts Java-style 2D row-major arrays into
the 1D column-major linearized arrays expected by the lower
level JLAPACK routines.  Using this interface also allows you
to omit offset and leading dimension arguments.  However, because
of these conversions, these routines will be slower than the low
level ones.  Following is the description from the original Fortran
source.  Contact with any questions.

c c takes the sum of the absolute values. c jack dongarra, linpack, 3/11/78. c modified 3/93 to return if incx .le. 0. c modified 12/3/93, array(1) declarations changed to array(*) c
