[Numpy-discussion] non-linear array manipulation

[Gong, Shawn (Contractor)]

hi list,

The following array manipulation takes long time because I can't find
ways to do in row/column, and have to do cell by cell.  Would you check
to see if there is a nicer/faster way for this non-linear operation?

for i in range(rows):
  for j in range(columns):
	a[i][j] = math.sqrt( max(0.0, a[i][j]*a[i][j] - b[j]*c[j]) )


thanks,
Shawn
