Class SLAMC5

java.lang.Object
  extended by org.netlib.lapack.SLAMC5

public class SLAMC5
extends java.lang.Object

SLAMC5 is a simplified interface to the JLAPACK routine slamc5.
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 seymour@cs.utk.edu with any questions.

* .. * * Purpose * ======= * * SLAMC5 attempts to compute RMAX, the largest machine floating-point * number, without overflow. It assumes that EMAX + abs(EMIN) sum * approximately to a power of 2. It will fail on machines where this * assumption does not hold, for example, the Cyber 205 (EMIN = -28625, * EMAX = 28718). It will also fail if the value supplied for EMIN is * too large (i.e. too close to zero), probably with overflow. * * Arguments * ========= * * BETA (input) INTEGER * The base of floating-point arithmetic. * * P (input) INTEGER * The number of base BETA digits in the mantissa of a * floating-point value. * * EMIN (input) INTEGER * The minimum exponent before (gradual) underflow. * * IEEE (input) LOGICAL * A logical flag specifying whether or not the arithmetic * system is thought to comply with the IEEE standard. * * EMAX (output) INTEGER * The largest exponent before overflow * * RMAX (output) REAL * The largest machine floating-point number. * * ===================================================================== * * ..
