xgraduate 
axis graduation
Syntax
[xi, xa, np1, np2, kMinr, kMaxr, ar] = xgraduate(xmi, xma)
Arguments
- xmi, xma
real scalars.
- xi, xa, kMinr, kMaxr, ar
real scalars.
- np1, np2
integers.
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)
