I have used a #define to reduce code size but it greatly increases the
compile time (from a few secs to 5 mins)
The #define is quite simple
#define UPDATE_VOL_SLICE(VOL,I,J,K, VAL)\
VOL[K][J][i] = VOL[K-1][J-1][i] + VAL\
+ VOL[K-1][J][I-1] - VOL[K-1][J-1][I-1]\
+ VOL[K][J-1][I-1] - VOL[K-1][J-1][I-1]
There are 2 more similar but bigger #define used by my program. They
are used a total of 20 times in the code.
Thanks

Anything wrong with a normal inlined function?

Some time back i had tested the speed of inline to actual code and the
speed was not same. The inline code was slower. Will try again and let
you know

Then it wasn't being inlined.
Check your compiler's documentation for inline code size and optimisations.
