Hi, This is for inform you about the first beta release for PyTables 2.2. You will find there some interesting new features, but no question that the most appealing one is the new `tables.Expr` class. You can think about it as powerful evaluator for generic mathematical expressions of NumPy array

Hi, Is there a way of performing vectorized ?axpy (daxpy) operations without making copies or dropping into C? i.e: I want to do big = (1,5000) A = np.ones(big,dtype=float) B = np.ones(big,dtype=float) a = 1.5 B += a*A without making any copies? (I know I could go A *= a B += A A /= a
