Performs complex division in real arithmetic, avoiding unnecessary overflow.
Syntax
call sladiv( a, b, c, d, p, q )
call dladiv( a, b, c, d, p, q )
res = cladiv( x, y )
res = zladiv( x, y )
Include Files
The FORTRAN 77 interfaces are specified in the mkl_lapack.fi include file (to be used in Fortran programs) and in the mkl_lapack.h include file (to be used in C programs).
Description
The routines sladiv/dladiv perform complex division in real arithmetic as
Complex functions cladiv/zladiv compute the result as
res = x/y,
where x and y are complex. The computation of x / y will not overflow on an intermediary step unless the results overflows.
