bsegin.m
EXAMPLE
FLOW
1)bred flattens data, saved: bredxxxx.dat
2)OCTAVE: segpic.m pics 1st breaks
segpic.m outputs bredxxxx.pic (tr,pic)
3)picrestore stdout stream:
picrestore bredk007.dat bredk007.pic >out.pic
Program picrestore adjusts pics, removing the flattening
4)bpic xxxx.seg 1 out.pic 0.0
(pics inserted into original file before bred, bulk
static=0.0 in bpic run )
