I am looking for a gradients calculating routine. I programmed one using
Rechardson's extrapolation method. But I found the accuracy is not so good.
Are there any kind soul have a good routine ?

Also I am looking for a routine which can differentiate equations symbolically.
Any comments are welcomed.

Thanks in advance,
