Since you never resize the array, it should be perfectly feasible to use `real[myLength] 
grad;` instead.  You might also try using 'foreach' but that doesn't solve your problem, 
just makes it more readable (IMHO).  One thing you might try is:

# real[] grad = new real[myLength];
# // ... loop ...
# delete grad;

I'm pretty sure you can use 'delete' with anything 'new'd, as in C++.
