DESCRIPTION

EXAMPLE

NOTES

NB  4-digit integer number which allows at most nine 
    rows on any side of the grid to be skipped.
    NB = d1*1000 + d2*100 +d3*10 + d4
    d1 = columns are skipped from left
    d2 = rows are skipped from bottom
    d3 = columns are skipped from right
    d4 = rows are skipped from top
    ex.:  NB=0000 include all borders (written as 0) 
      NB=1111 omit one row all around the grid 
      NB=2241 indicates that the 2 columns on the left of a, 
        2 rows at the bottom,  4 columns at the right 
        and 1 row at the top are not operated on and the 
        corresponding rows and columns of R are left 
        undefined by the routine
