axis graduation



Calling Sequence
~~~~~~~~~~~~~~~~


::

    [xi,xa,np1,np2,kMinr,kMaxr,ar]=xgraduate(xmi,xma)




Arguments
~~~~~~~~~

:xmi,xma real scalars
: :xi, xa, kMinr, kMaxr, ar real scalars
: :np1,np2 integer
:



Description
~~~~~~~~~~~

`xgraduate` returns the axis graduations which are used by the plot
routines (with pretty print flag enabled). It returns an interval
`[xi,xa]` which contains the given interval `[xmi,xma]` and such that

`xi= kMinr*10^ar`, `xa=kMaxr*10^ar` and the interval can be divided
into `np2` intervals and each interval is divided in `np1` sub-
intervals.



Examples
~~~~~~~~


::

    [x1,xa,np1,np2,kMinr,kMaxr,ar]=xgraduate(-0.3,0.2)
